Pop a cap

Pop a cap is a slang term, which relates to the action of a operating a firearm with the intent to do bodily harm. As it relates to film, the phrase became a staple of American youth pop culture after it was heard in the 1994 action/crime drama Pulp Fiction. In the film, the character of Butch Coolidge screws over his business partner, crime boss Marsellus Wallace. When giving instructions to his underlings about how to handle Coolidge, Marsellus says, I'm prepared to scour the the Earth for that motherf**ker. If Butch goes to Indochina, I want a ni**er waiting in a bowl of rice ready to pop a cap in his ass." Ever since then, it has become cool for white kids to say "pop a cap".
