This is when a girl gives u head, then you bust it in her face, rip off your pubes and trow them on her face so they stick.
"That girl's such a freak, I gave her a gorrilla mask and they are still sticking there"

The act of giving your loved one a facial and following that by tossing a handful of pubic hair in their face so that the hair sticks and gives the realistic appearance that one has suddenly been transformed into a gorrilla.
The masquerade ball required us to wear Gorrilla Masks, complimentary upon request.
