Motorcycles are broken down into general categories. Off road, Track, Cruisers ( incl. Harley Davidsons, Kawasaki Vulcan, Yamaha Roadstar), Sport Touring (Honda ST1300), Touring (Honda Goldwing) and Sport.(Honda CBR600, Yamaha FZ6) Sport bikes are very fast highly mobile bikes where the rider is low and leaning forward. The bike is generally a cafe race style. A Crotch Rocket is the slang term for Motorcycles of the Sport category. The term is derived from their incredible speed. The previous definition of "Non-Harley's" is patently false. I have a Honda Goldwing and it is definitely not a Crotch rocket.
N: referring to the family dog, who steals your sister dirty underwear out of the hamper, then eats the crotch out of her soiled panties. Most crotch muncher’s prefer, period panties, or ones with lots of goo in them.
Addy steals Danielle’s panties and eats the crotch out of them.
Hillary's panties are a Crotch muncher's gourmet snack.
