phlannel pj pants

When one sexual partner shaves themself (any body hair, but particularly pubic) and then applies a layer of Vaseline to their par tner's legs, followed by the hair. This is done pre-coitus and is often used in gender reversal fantasies.

Guy 1: Hey, dude, where did your leg hair go?

Guy 2: I gave my girl a pair of phlannel pj pants before we had sex last week. The sex was great, but the cleanup was a lot to deal with.
