The dive

When a "crack addict" takes a shit, and is out of crack so he/she reaches into the toilet and picks apart her/his feces in order to get the morsels of leftover crack and re-use them.

Guy 1: "Yo where's Matty? I got some dope shit he should try"
Guy 2: "Aw fuck man you just missed him, he went to the bathroom. Probably in there getting ready to do the dive"
