A sexual move whereby a man, about to consummate a masturbation session, shits into his free hand and then hurls the mess in the direction of some victim.

The move is obviously hyperbolic in nature, and is used to describe someone attempting or doing something equivalently asinine in nature.
"I can't believe he showed up at your party and then threw up on your girlfriend."
"I know. Steve is such a chocolate thrower."
