facehole
A facehole is someone who's not just an asshole, but an assface who talks out of their ass and makes everyone around them suffer.
They post a comment about your hair and say, 'You look like a raccoon.'
They argue with you about the meaning of life and say, 'You're the dumbest person I know.'
They send you a message and say, 'You're the worst, and I hate you.'
