[good guy], [bad girl]

A type of couple that tends to be either a lovely power couple or a couple with a toxic, dysfunctional relationship. One of the things that prove that usually opposites attract

Good guy: Do you know that cliché about the opposites and shit?
Guy2: Yeah bro why u ask?
Good guy: dude I think I'm falling for Tanisha
Guy2: well, good guy, bad girl, they're either a perfect or an horrible pair.
