Foxxy is hinted to have had a very dysfunctional upbringing. It is indicated in several episodes that her father abandoned her at a very young age (she states in "The One Wherein There Is a Big Twist", "Mama didn’t raise no fool, and Papa didn’t raise me at all!"), and might also suffer issues of child molestation. In "Hot Tub", Foxxy mentions that her father has never kissed her, and in "Clara's Dirty Little Secret", she implies that her father told her that her vagina is a "horrible place". In "Freaks & Greeks", Foxxy's father is said to have left for cigarettes 21 years ago (Foxxy is 23), and it is sometimes indicated she expects him to return any day. In "Ghostesses in the Slot Machine", she claims that her mother kicked her out of the house when she was 14 years old for dressing like a stripper.
In the episode "Nipple Ring-Ring Goes to Foster Care", Foxxy is finally re-acquainted with her father, who turns out to be Uncle Benny of Uncle Benny's rice; however, at the end of the episode, he abandons her again. The same episode indicates that Foxxy's mother is an actual fox, directly contradicting previous episodes which indicated her mother was human.
A much-exploited gag on the show is Foxxy's bewildering amount of life experience. Despite her seemingly young age, she has had several abortions (see Sexuality below) and has carried at least three children to term, one of whom may have in turn become a parent themselves. Two of her children, named Kwametta and Ray-Ray, were taken away from her by Child Services and renamed "Heather" and "Raymond-Raymond", causing some animosity between her and Child Services. In the episode "N.R.A.y RAY", Ray-Ray finally appears, but he is identified as Foxxy's grandson; it is unclear whether Foxxy has both a son and a grandson named Ray-Ray or whether this is an inconsistency. After catching Ray-Ray burglarizing the Drawn Together house, Foxxy scolds him, "I did not not raise yo' papa to not raise you to be no criminal!", a reference to her family's general proclivity toward parental absence.
Foxxy also has a son named Timmy who has become the subject of a running gag on the show,: whenever Foxxy discusses something unfortunate happening, the show often cuts to a quick clip of her in the confessional saying, "Poor little Timmy. Mommy misses you". In "Dirty Pranking No. 2", Foxxy scoffs at Clara and Spanky's attraction to one another, saying, "Daddy's little girl falling for some bad boy, and then she'll go and get herself pregnant and be forced to sell the child on the black market to pay the bills"; at this point, Foxxy says the line for the first time. In "A Tale of Two Cows", Foxxy tells Wooldoor (after Live Action Cow is discovered to have rabies) that he needs to shoot Live Action Cow right between the eyes while it yells, "Mama! Mama! I ain't got no rabies, I is just brushin' my teeth as you says!"; she then says the line again, implying she did that very thing with Timmy. Also in "The Lemon-AIDS Walk", Foxxy states that Timmy is the last person she ever thought she would see again before cutting to the clip once more. In "A Very Special Drawn Together Afterschool Special", she says that Timmy is in an orphanage in Kansas City, Missouri; however, when this is stated, she is roleplaying as a prostitute, so that information might not be canon. The child's actual fate has not been clearly established.
Foxxy's sexuality is her most exploited character trait; her character is revealed to be not only extremely promiscuous, but also rather kinky. Foxxy is bisexual; though her preference is men, she clearly enjoys relations with other women as well, as evidenced by her behavior toward Clara in "Hot Tub" and her own bandmates in "Captain Hero's Marriage Pact". She has crushes on Star Wars character Lando Calrissian and actor Denzel Washington. In "Requiem for a Reality Show", she has a short-lived BDSM relationship with Captain Hero, a relationship in which she assumes the dominant role. In "Unrestrainable Trainable" she has a threesome with Spanky Ham and Toot Braunstein, again assuming the dominant role. Many jokes have been made regarding Foxxy's sexual habits. She is implied to have sex so frequently that she is so used to being pregnant that she treats it completely dismissively (she once suggests, seemingly with no external evidence, that there is a good chance she is pregnant at the moment). She has abortions with such regularity that in "The Lemon-AIDS Walk", she is shown to save money in a jar for that specific purpose. In "Alzheimer's That Ends Well", she hands Clara a tampon; when Princess Clara asks how to know when to take it out, Foxxy has no idea what she is referring to. In "Wooldoor Sockbat's Giggle-Wiggle Funny Tickle Non-Traditional Progressive Multicultural Roundtable!", she gets her period seemingly for the first time ever.
Foxxy has an extremely elaborate masturbation ritual which involves heavy use of props, such as a lightsaber. When she masturbates, her orgasms become fiery explosions. Beginning in Season Two, her character design was tweaked so that her nipples always stick out (in the first season they stuck out only when she was excited) when she is in her usual outfit. She has also revealed that her taint is made of bacon; while she claims at first the producers deliberately edited her to say this (with, as she put it, their "god damn white flashes", meaning the dramatic flash seen when switching scenes), she quickly confirms it.
Foxxy largely serves as a vehicle to make fun of black stereotypes, such as being sexually promiscuous, spending money foolishly on frivolous luxury items and lottery tickets, and being unable to speak standard English. She frequently refers to herself in the third person. Foxxy's skills with written language are also poor; for instance, the label on the abortion jar she uses in "The Lemon-AIDS Walk" features an "R" which is written backwards, and the paper on which she attempts to write song lyrics in "Captain Hero's Marriage Pact" features spelling of a similar nature. In "Spelling Applebee's", Toot teases Foxxy that she is illiterate; however, Foxxy replies that she can "read and write real good". Foxxy then reveals that she was once a champion speller, but vowed never to spell correctly again after a violent racial incident that took place at her last spelling bee. In the episode, Foxxy overcomes her fear and begins spelling perfectly again. In "Unrestrainable Trainable," in order to give Wooldoor Sockbat CPR, Foxxy is required to remove her grill. Once she sees that Wooldoor is okay, she says in a refined upper class accent, "Capital--Thank goodness I am trained in cardiopulmonary resuscitation!" She then replaces the grill and shouts in her usual voice, "Mouf-ta-mouf, y'all!"
Despite her role as the "Sassy, Trouble-Causing Black Woman" on reality TV shows, Foxxy ironically acts as the voice of reason on many episodes, a role seemingly inherited from her prototype Valerie Brown. This may only be a relative factor, as the other characters tend to be less stable than their reality TV counterparts. Though she isn't book smart, she has arguably the most common sense of the housemates, and acts as the unofficial leader of the group. Foxxy's role is often that of the house's backbone, holding the other characters together or uniting them in times of disagreement or strife. Wooldoor even describes her as "the only one in the house who isn't completely retarded". Foxxy has many catchphrases that she uses on numerous occasions. her most common ones are "Be that as it may," which she usually states whenever someone points out a logical flaw in her argument or "Not for real-real, just for play-play" which is occasionally used. She often states "Oh Lordy" when something goes wrong.
In Season One and the first few shows of Season Two, she was the character who received the most airtime, though as Season Two progressed, she was surpassed in this regard by Captain Hero. In the confessional scenes her age is revealed to be 23; however, this would make her about one year old at the time "La-la-la-la Labia" supposedly came out.
Her relationship with Princess Clara is complex. She is repulsed by Clara's racism but doesn't hate her, realizing Clara is for the most part simply parroting what she has been taught rather than acting out of genuine hatred toward other races and religions. However, that hasn't stopped them from fighting viciously on occasion. In spite of this, she seems to consider Clara a friend, as evidenced by the episode "Clara's Dirty Little Secret", when she went to great lengths to protect her from the violent intentions of the other housemates. Earlier in the episode, Foxxy tried to encourage Clara to more openly embrace her sexuality, only to learn that Clara's vagina had literally been transformed into a monster.
While the show's first season focused on the pair's friendship, interaction in the second season between the two focused more on how Foxxy detested Clara's insensitivity (which resulted in Foxxy attacking her a couple of times). However, the lack of balance in this regard may also be due to the fact that neither character assumed as prominent a role in the second season as they had in the first, and thus were limited to mainly comedic moments. It is suggested in the first episode that there might even be a sexual attraction between the two, as they end up making out three times in that episode. However, except for "Ghostesses in the Slot Machine" (when they make out while stripping in an attempt to make Clara's father notice them) and "Charlotte's Web of Lies" (they are making out before Captain Hero kills them; this is part of a running gag where the women act wild whenever the men are not around), this suggestion has not been repeated in subsequent episodes.
