An insult, made up by the people of New Jersey. It is calling you a dirty vagina. A muff is a vagina and cabbage is..cabbage. Therefore, it is either a dirty vagina or a vagina with cabbage in it.
1. A huge, gaping maw of a vagina with not only inner and outer labia, but several folds of skin in between said labial regions, resembling a cabbage; quite possibly smells like old rancid cabbage as well.
2. Non-sensical term coined by South Park's episode called "It's a Jersey thing". Mostly uttered in anger.
Angry hair dresser: That whore is gah-bage! That muff cabbage thinks she's hot shit, but she's just nothing, she's just a cabbage!!
Innocent bystander: What the fuck is muff cabbage?!
Vulgar term for a woman's horribly overused, flappy, gaping, pungent, bacterial-vaginosis infested vagina.
Instead of saying "muff garbage", clowns from New Jersey sound like they're saying "muff cabbage" because of their ridiculous accent. Coined by a recent episode of South Park entitled "It's a Jersey Thing" in which they make a parody of the useless wastes of life who appear in the show "Jersey Shore" Which should never be watched by anyone. Ever.
"YOU'RE GAH-BIDGE! YOU'RE MUFF CABBAGE! YOU GOT CABBAGE IN YUH MUFF! YOU GOT CABBEGE.. IN.. YOUR.. MUFF!!!"
