Flapsize

A play on the word "cap-size", to flapsize a woman, is to prevent her from advancing with a man. It is the female equivalent to "cock-block"

Why don't you go over there and flapsize your sister by threatening that guy she has a crush on!

Fapsize

To masturbate so vigorously that one loses one's balance. A portmanteau of fap and capsize.

Man I was polishing the wedding tackle in the shower and just when i was about to chuck the muck I fapsized! Almost killed myself!
