A vanillia gorilla is when a guy spunks on a girls face and then proceedes to grab a handful of pubic hair and throw them on her face, hence creating a white gorilla scene.

This is what you call a white guy who tries to act like an Asian. There is a high probability that he will try (usually with little success) to get with an Asian girl. Other indicators are that he will like anime, manga, and drive a ricer.
Look everyone, here comes Vanilla Rice with his riced-up civic. Pretty soon he'll be talking about Goku and stuff. And he's white, not Asian.
