look up any word, like fleek:
(American): The art of throwing a full bag of chips at an adversary's face.

The history of face-chipping dates back to Pre-Potato famine Ireland's more brutal practice, in which rivals would hurl bags of spuds at each other's faces as shows of domination and revelry.
Man did, you see that face-chipping of Dave Baron today in Vandy! That was sick brah'!
