"Just Lose It" is a song by American rapper Eminem, released in 2004. It was the lead single from his worldwide hit album, Encore, which was also released that year. The song caused controversy as its lyrics and music video parody Michael Jackson, who was being accused of child molestation at the time. The song also pokes fun at Beavis/Cornholio, MC Hammer, Madonna, Mr. Bean and others. It also heavily spoofs Pee-wee Herman, going as far as imitating his signature shout during the chorus and Eminem dressing like him in the video. The song reached number one in the UK, Australia, and New Zealand, and number six in the United States.
Two skits regarding the Michael Jackson controversy were included on Encore, "Paul (Skit)" and "Em Calls Paul (Skit)". The matter was also mentioned in a song from The Anger Management Tour 3 Mixtape entitled "Get Off My Nuts".
At the beginning of the song there is a lyrical excerpt from Eminem's 2002 single "Without Me" about how "Shady's back". The line "Snap back to reality. Look! It's B. Rabbit" and "You signed me up to battle" refers to "Lose Yourself" and Eminem's character in the movie 8 Mile. In the second verse of the song there is a line "So fellas, fellas..." is a reference to Sir Mixalot's song "Baby Got Back". In the chorus of the song where he says "Girl you know you're my world" is from the chorus of his song "Superman" from his hit album The Eminem Show.
The video contains a parody of a rap battle scene from 8 Mile in which it is Eminem (as he appears in the movie) versus Eminem (as his opponents would seem to appear). It also contains several scenes where Eminem is walking down the streets naked.
