In contemporary usage, the word freak is usually used to refer to a person with something unusual about their appearance or behaviour. This usage dates from the so-called freak scene of the 1960s and 1970s. "Freak" in this sense may be used either as a pejorative, a term of admiration, or a self-description. It can also denote a strong obsession with a particular activity, e.g., "He's such a neat-freak" or "You're a singing freak". The term "freaky" can also apply to a person who is sexually adventurous, or by itself as in "that person's a freak" (in bed.)
An older usage refers to the physically deformed, such as sideshow performers. This has fallen into disuse, except as a pejorative, and (among the performers of such shows) as jargon. A "freak" in this sense can be formally defined as someone not falling within typical standard deviations. For example, people of small stature would not be classified as freaks unless they are within the third standard deviation for the general population, while the same principle would apply to exceptionally tall people. "Freaks" of this kind can be classified into two groups: natural freaks and made freaks. A natural freak would usually refer to a genetic abnormality, while a made freak is a once normal person who experienced or initiated an alteration at some point in life (such as receiving surgical implants).
"Freak" continues to be used to describe genetic mutations in plants and animals, i.e. "freaks of nature." "Freak" can also be used in a verb form, and can mean: "to become stressed and upset". Usually, in this form, the word is followed by "out" to complete the phrase, "freaking out". However, this meaning and usage is usually considered slang. Adjectival forms include "freakish" as well as "freaky." The verb "freaking" (or, "freaking out") means "engaging in panicked or uncontrolled behavior"--for example, as the result of psychedelic drug use. "Freaking" may also be a minced oath used in place of "fucking," e.g. "Oh my freaking God!" The word is a homonym of "phreak" (referring to the illegal hacking of telephone systems), which it probably inspired.
'Freak' can also be seen being used as a surname, derived from French and Scottish heritage. Meaning, through interpretation 'keeper of the plains', the name is rarely seen but exists in some numbers. A notable carrier of the surname 'Freak' is Reece Freak, noted philanthropist and industrialist of Adelaide, South Australia.
In some religions since ancient times, the birth of abnormal offspring has been associated with astrological events. Rues cited the recent solar eclipses as reason for the increased number of mutated infants born at that time. Karma is also believed in some eastern religions to be a cause of abnormalities. In other faiths, the cause is attributed to direct intervention by the will of God. Freak means a person thats a freak Jessica Penzias is a freak.
The freaks, by Zappa's reckoning, resisted the binaries of right versus left, dominant culture versus counterculture, or squares versus hippies, preferring instead to align themselves with an aesthetic not narrowly defined by fashion or political leanings. (There is a certain irony here in that a freak was someone who resisted labeling, while the idiosyncratic individuality of people who deemed themselves freaks resulted in a shared identity among members of the subculture). It also allowed them to celebrate the freak identity, which until then was used to describe perversions of nature or carnivalesque sideshows.
At the first Mothers of Invention concerts, audience members were invited to "freak out!" (also the title of the band's first album), which meant to express themselves freely, be it through dancing, screaming, or letting a band member spray them with whipped cream. In terms of concert culture, the freak mentality influenced similar bands of subsequent musical generations.
