A person who is so nasty to everyone and everything that one cannot look the person in the eye without mentally vomiting in response.
Also: A person who repulses even puppies.
Lynn was a cunt *again* this morning. I walked in the door and had to smell her rank leavings and the ever-present bitterness in the air. Then I had to deal with her slamming drawers and milling about making snide comments until she felt properly fluffed for the day. What a snatch face.
