A girl who grinds down on your dick so hard while she's riding you that you get chaffed and sore. Originally from a Frank Zappa song.
1) That girl I banged last night was a Jones Crusher. My dick was so raw when I woke up it had scabs growing on it.

2) She's a Jones Crusher, Jones Crusher; Deadly jaws, better get the gauze...
