Prostbite

A word derived from a combination of prostate and frostbite, prostbite may occur when a gay man sticks an icicle up his anus and uses it as a dildo. This results in the man's inner asshole contracting frostbite.

Guy 1: Last night was so fun, but I think that icicle I used gave me prostbite.
Guy 2: Dude wtf.
