Thomas is white, Hispanic, and Italian, therefore he is a mutt.

a non-purebred dog. since they aren't subject to the inbreeding that purebreds usually are, they tend to be healthier. all around very good dogs.

term used to identify someone as multiracial; pretty derogatory word for a multiracial person, at least in the eyes of someone who is multiracial him/herself (because of the word's use in labeling a dog as inferior as a result of impure breeding)
i think it is obnoxious of you to call me a mutt; i'm not inferior to you because my parents are two different races.

A mutt is a person of a multi-racial background, depending on who you are talking to it can be considered offensive and/or derogatory. In a lot of cases people don't take offense to it(I personally call myself a mutt all the time) Just be careful who you call a mutt, some people won't take it very well.
Ex 1)

Anthony: what are you, you look Hispanic?

Me: I'm a mutt...

Anthony: Me too!

Ex 2)

person1: what is she, I can't tell?

person2: I'm not sure, she's some crazy mix.

person1: Oh, so she's a mutt.

person3: Who are you calling a mutt, you're no better than me just cause I'm multiracial!

Ex 3)

Guy: Wow you're gorgeous, what are you?

Girl: I'm Guyanese, Irish, Indian, and German.

Guy: So you're a mutt.

Girl: yup and damn proud of it too!

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"
