Neck Chop 

A small, swift chop to the neck delivered with the knife edge of your hand, in a ninja-like fashion. Usually followed by the fast call "neckchop!" *Used best on targets who are sipping a drink, dragging a cigarette, or looking upward*

Girl: "Hey, come on give me a kiss."
*whack*
Girl: "Neckchop!"
Guy: *cough* what the fuck.
Girl: "Hahaha."

Well chop off my head, and shit down my neck! 

An indication of genuine, but not extreme, shock or surprise. Best said in a Southern accent.

More savvy users can infuse the phrase with sarcastic meaning, as a variant of "Duh!"
