Gays, Blacks, and Your Maw

Alright, listen up, you chucklehead. This joke is basically listin' off groups of people and then throwin' in "your maw" (that's slang for your mom), implying she's somehow in the same category as those groups. It's like sayin', "Apples, oranges, and your mom!" Get it? Bet you didn't, ya goofball. You're probably one of those guys who wears socks with sandals.
