When a man shaves his pubic region while saving the pubic hair, then proceeding to ejaculate on a females face, he then slaps her in the face with the pubic hair causing the hair to stick to the ejaculate on her face. The man will then proceed to slap her in the face with his erect penis.
Bobby: I gave your mom a Gorilla Slap last night! Now she has a fucking beard!

Josh: hahahaha, my mom's a bitch anyway!

Get the Gorilla Slap mug.
Also called the Bloody Gorilla. Same as the Gorilla Slap, except its the female that stands holding a sprinkle of her freshly shaven pubes. Requires that time of the month conditions. Subsequent and corresponding boner face-bash is replaced by enforced anaerobic stawberry jam muff diving.
Derek sure loves Melissa. After he cheated on her again, he willfully submitted to a Lady Gorilla Slap to let her blow of steam and thus win back her favor.

Marge is quite the butch. When the crimson tide comes rolling up, she enjoys giving her conquests ye olde Lady Gorilla Slap.
