smilefucker 

A person who wields their potent hostility through their forced, gigantic, toothy and maniacal smile.

I used to go out with that smilefucker and he seriously never turns that shit off.

Smilefuck 

You've been smilefucked when somebody smiles and agrees to do something for/with you, when they have no intention whatsoever of actually following through with said commitment.

This jackoff rep from <insert carrier here> keeps calling me asking for quotes - I usually tell him every couple weeks that he'll be getting some opportunities in the coming weeks - no shot! Classic smilefuck.

He seemed very open to the customer request. Or he was just smilefucking us.
