A variation of the gorilla mask, a reverse gorilla mask is a sexual act which involves two men. The "donor" first cuts his facial hair. He then proceeds to cum on the shaved testicles of a male friend, the "recipient". The donor then sprinkles his facial hair onto the recipients testicles.
"Dude, you shaved!" "Fuck yeah, man! Last night I totally gave Anthony a reverse gorilla mask!"
