What ungroomed ladies and gentleman have going on in their pants. Pubic 'fro. It is an outdated practice that people look back on with some embarrasment that they ever conducted themselves in such a fashion. The only people that enjoy Disco Fever are people that have never experienced a smoother style, or people that can't let go of the hairy, disgusting past.
So, I undressed her and it was like, Boom!! Welcome to the 70's! Disco fever going on in Gem's pants!
