Man white

Typically a straight white male who sleeps around, never actually getting themselves into a commited relationship (or otherwise just a thot)

They're also probably racist and cant take it upon themselves to realise they can be wrong or want to educate themselves further on any subject that might discourage any of their behaviour

Person 1: wow your brother is such a man white
Person 2: yeah i know, he was talking about another girl he had sex with at the dinner table last night
