Sad Hat
The instance when your dick is trying to enter a busted up vagina and the flabby labia fold in on the vaginal entrance so your dick can't get in but is just hanging out wearing a "sad hat" of floppy pussy folds.
Last night I was hanging with that ho Jessica and when we tried to have sex, I couldn't get my dick in her pussy cuz those nasty meat curtains just folded up on my dick like a sad hat.
