Fap cap 

When you're fapping, you reach your climax, but pull your foreskin over your dick so none of the cum comes out. Note: does not feel as good as normal fapping.

Bro, I was in art class today and I needed to rub my nub real bad so I fap capped.

Billy: No- I bet he's busy at home choking the chicken again, that horny bastard.
