Machunk
A type of rack in ruit. It’s made of four cups and shaped like a sideways diamond. People call it a machunk because it’s loose and looks like a vagina. It’s also called the slut, the skankbag, or the reverse diamond.
"I got a machunk and my friend said I looked like a slut. I didn’t care, I was too full."
"He asked for a machunk and said it was the only way he’d go out with her."
"I called it a machunk and my teacher said I was being too loud."
