Cock blocking yourself, getting into a situation where you fuck your own stupid ass over.
"Stepping on your dick"

Having your best friend Joseph remind you of your dumb ass getting busted when you were cheating on your girlfriend, while you all are having a lovely dinner together.

Noe kept "Stepping on his dick" because he was trying to fuck his girlfriend and a neighbor slut, Define Slut:(Side piece) or (Daddy's little cum dumpster). However he wasn't smooth enough and he kept getting busted while inserting his junk up into his sluts love pipes or piss flaps.
