Normally a stubby cock, where the head of a cock goes back inward and looks like your circumcised cock never had the procedure in the first place. Looks like a toque and happens when you wear tight ginch or have a fat roll in your ginch pressing on your cocker all the time.
I've gained a lot of weight since I finished high school and whenever I take a piss I have to stretch out my bird a few times because I get cave cock.
