Bust a nut

A slang term, used in place of the more "correct" term for ejaculation. The term originated from when sperm would bust from the testicles (nuts). Not to be confused with "bust your nuts" meaning to smash the testicles.

"My roomate tried to steal my girl last night, so I bust a nut on his bed."
