premature assumption of the complete and utter truth in one's thoughts, opinions, and actions. Cocking your gun with no ammo. Gunning your cock at anything that moves.

A feeling of confidence, superiority, greatness, and swagger only obtained by pure animals. This "attitude " or "lifestyle" in fact has absolutely nothing to do with the size of one's penis, but is more a way of life for wildmen.

Frat guy #2:"Yeah, I know! He's such a cocksure wildman!"

The confidence you have knowing your cock is doing the damn thing.. You try "taboo" things and she just goes with the flow...You're so "Cock-Sure" she just doesn't say no...
"Damn baby....I've never done that before.... But you were so "Cock-Sure" I couldnt say no"
