Refers to a foul, fishy smelling vagina. A combination of the term hoo hoo and sushi. If one is described as having a "hooshi", then one should probably consider taking a bath or something.
I would have totally done a muff dive on that chick with the tramp stamp, but once I got a whiff of her stank-ass hooshi, I threw up a little in my mouth.
