a girl who is gross, but a hottie. She burps, farts, scratches her butt and when she picks her nose or ears yells, "Jackpot!"

Particularly desirable as a girlfriend as she's hot... and being gross herself, she can never be disgusted with you because she is disgusting herself.

Marry her.
You hit the jackpot, brotha! You’ve got a girlfriend who can never get on your case for being disgusting because she’s even more disgusting. Sonny is gross and a hottie. She’s a Grottie!
