An utter Abomination. The foulest of all creatures known or unknown to mankind, often the "cute friend" a girl tries to set you up with. Has the comparable sexual attraction to a menstrating Jaba the Hutt. Typically large enough to contract her own gravitational pull, with the blubber capacity to be used as a flotation device in dire circumstances. See Titanic. The equivalent of a "0" on a 1-10 rating scale, assuming negative numbers are not allowed.
"I would rather face fuck a pitbull than kiss that Grindlesnatch."
"I found myself being drawn to her physically. Literally. In a badfucking way."
A ski lift of the 'Poma' (manufacturer) or 'Platter' type, consisting of a single pole/basket seat that you stick between your legs and pulls you up the track to the top of the ski hill. It 'grinds' your winkie (genitalia) if you are not careful or your ski pants are not thick enough. Not really true as I used to ride it at Paskapoo when I was a kid, and my winky survived. As proof, I have a daughter, Sarah, who came up with this definition when she was 7.
