1. A remark made to someone being hauled off to jail, particularly someone you dislike. Once in jail, you imply that if the person (a male) drops a bar of soap in the shower, they will be forced to bend over and retrieve it. Thus, with there buttocks spread and in clear sight, will be subject to anal rape by a fellow inmate.
"Don't drop the soap!" I yelled as the burglar was taken away by the police from my home. His eyes began to tear up as he anticipated that hot, steamy shower.
A comment saying used it reference to being ass raped by a well endowed black man when reaching for soap that you "accidentally" dropped.
Tyrone: "Don't drop the soap!"
Frank: "Oh no! I dropped the soap!"
*looks around to make sure Tyrone saw*
Tyrone: "Hey. You should really get that"
*Frank bends over*
Tyrone: "Surprise, Motha' Fucka"
Frank and Tyrone are actually secret lovers but Tyrone is afraid and ashamed of their love. Frank is Tyrone's Prison Bitch
Good advice for prisoners:
If you drop the soap in the prison shower, you'll be forced to bend over and retrieve it. Ergo, with your bum out and in clear sight, you're gonna have to take it in the bum from a sick, psychotic fellow inmate.
Don't drop the wallet
