chocolate drop

When a black man with a fat juicy ass busts it down usually with little to no clothes on. Usually performed by thugs or other menacing figures in hood-like areas.

Person 1: "Hey I hear that you're a real thug, you wanna do the chocolate drop for me? I'll pay."
Thug: "I don't do that faggot ass shit, fuck outta here."
Person 1: "Woah now I have $500 buddy, this can be all yours if you do the chocolate drop with that thug ass."
Thug: "Ok fine."
