dog bitter

A girl or boy who is very ugly in the face. Typical dog bitters have an ok body but the face is deplorable. They usually turn to making out with a dog cuz they're just that ugly.

Guy1: Check her out she has a nice ass.
Guy2: Wait for it....(she turn's around)
GUY 1/2: Damn she's a dog bitter,fuckin ugly. What a shame, that's a waste of a perfectly nice butt on a face like that.
