prom knob 

A sexual technique in which the male, instead of applying the condom in normal fashion, places the condom completely on, and then folds it inside out back over the tip, repeating until he has created a multi-layered latex "knob" over the head of the penis.

Mitchell prom knobbed the shit out of that bitch. He even used two condoms!
