Slapped the fuck out yo mouf

What happens when someone is served an open palmed disrespect, often utilizing a tool. Is seen as a deserved act of revenge after a period of humilation.

In that movie Wanted, the main character slapped the fuck out yo mouf when he bashed his cheating best friend with that keyboard. It said, "Fuck You"
