Top Definition
The horrible stench that comes from the rotted mouth of Stupid Face. It is similar to the smell of rancid goat feces or spoiled goat cheese. In small circles, it is also referred to simply as GB.
Stupid Face walked in here the other day, and she had the worst Goat Breath (GB) I've ever smelt and it made me puke. She must have spent half her day servicing a billy goat to achieve that stench. God I hate Stupid Face.
