What is Exfoliate?
1.
Actually means to clean yourself in such a way to remove dead skin cells and then remoisturize the skin.
Now that the real definition is out of the way, let's do an Urban definition!
When a man is pounding a chick doggy-style near a toilet. The man grabs the chick by the hair and shoves her head into the toilet, flushing it and giving her a swirley! Now that the face is cleansed, it must be moisturized. The guy then yanks her head out of the the toilet by her dripping wet hair, pulls his dick out of her, and blows his load all over her face.
I'll exfoliate Mel Gibson, how 'bout that?

Daughter: "Dad! What are you doing??"
Mel: "I'm...ah...exfoliating"
