butter face

when a woman is seemingly attractive but ends up having an attractive body with an f'ed up face.
"Don't be a butterface, where evrything is good, 'butther' face"

Person #1: damn, look at that chick!

Person #2: *chick turns around to be hideous* ugh, you mean that butter face?

Person #1: dammit, the cake is a lie.
