After a cum facial the recipient is surprised with a fist full of pubic hair. A GORILLA MASK is not complete if the receiver doesn`t yell out "GORILLA MASK" as they're throwing or slapping the pubes on the recipients face.
(In the distance)... "GORILLA MASK!"
"What was that?"
"Somebody just got GORILLA MASKED"
"A cum facial followed by a fist full of pubes."
"Huh. Let's go back to my place. I wanna try something out."
