That stacey chick, what a bitchfacewhorebag! Hope she jumps off a fucking roof and dies. I hate that nasty whore so much, she is such a motherfucking asshole of a bitch!!
The words uttered by anyone who has just slammed their thumb/finger with a hammer. Can also be used as a derogatory term when speaker is stumped for a suitable comeback.
