Smut

Any girl that a guy is having sex with. Doesn't have to be a slut, whore, thot, bimbo, baby girl or wife. Any girl that a guy is having sex with is his smut during that time. She might be a one night stand or life long wife. Submissive or dominant. For a straight male that finds a girl attractive and fucks her, she is a smut.

Guy during sex: That's a good smut, keep sucking.

Guy with friends checking out a girl: Now that girl would make a great smut.

Married guy with friends: I mean I like her as a wife and mother, but she's not a good smut for me anymore. I'm thinking about divorcing her and getting with a younger girl.

Girl during sex: I wanna be your good smut daddy!
