1. a really ugly sad excuse for a girl, a mutt thinks she can get everyone, and is extremely jealous of any other girl. guys only go for mutts because they are an easy kill, but mutts can never actually date a guy, because who would want to date one? mutts usually kiss other girls for male attention, but they only kiss eachother, because they can't get anyone else.

2. a girl who gets eaten out by her dog every night because no one else will. (bestiality)
"fuck, that girl is soo ugly. she's such a mutt"
"yeah, 20 bucks says she goes home and gets her dog to eat her out"
"poor dog"
