It is when a man puts his penis inside his girlfriend's, OR BOYFRIEND'S asshole, while quoting Steve Austin lines, pounds rapidly in their anal cavity. Suddenly, the pitcher feels a sharp pain in his penis tip, so he pulls out, and what does he find? A little chunk of shit lodged in his peehole. That, my friend, is a Dirtball Digger.
My friend Brett got a Dirtball Digger from some fat chick who just had Chipotle. Gross.
