Butterfinger 

When a male looking to spice up his sexual experience grabs a cold stick of butter and shoves his finger through the center of the stick, then proceeds to finger his woman until the butter melts from friction and sexual heat, granting him a dairy-based lube upon which he uses to dick his woman down.

Man #1: Hey how was the sex last night?
Man #2: I Butterfingered her and it changed her life.
