A tactic used by women to prevent themselves from doing something regrettable when out at a club, bar, party, etc. This involves purposefully not shaving her legs (or other parts) before going out so that she will stop herself from hooking up with someone to avoid the no-shave shame the morning after.
Crystal: Man, that guy was all over you! Why didn't you leave with him?
Kayla: I cant, no shave behave!
