A device that boys w/ small penis's use to completely erase their brains or smear them all over the road. This device has the ability to make boys think they are cool when in reality they end up acting like idiots and killing people on the road after masturbating to "Biker Boyz". The one redeeming quality is that Darwin's Theory has full effect on this crowd.
Watch the evening news on most any summer afternoon to see an example of one of these boys riding crotch rockets becoming organ donors.

1. (noun) A motorcycle falling under the class: "sport bike". Traditionally used in motorcycle racing because of their high performance, crotch rockets are instantly recognizable due to the fact that the engine is completely covered by the body of the bike, and the operator looks as though he is "riding a rocket". Visualize a person sitting horizontally on a rocket flying through the air, now imagine that rocket is slowly becoming a motorcycle, but the rider maintains that "rocket riding" position. Now stop using your imagination and you have the visual of a crotch rocket. They're fucking gay. Unless you are using them for racing, you should not be riding one.

Most likely the rider is a complete douchebag who spent too much money on some Japanese piece of shit so he can weave through busy traffic and piss people off. Basically the sole cause of the bad stigma attached to motorcyclists, because of their disproportionally high accident rate and jackass driving habits.
"A Kawasaki Ninja is a crotch rocket."

"Dude I borrowed my buddy's crotch rocket to go to _____________ last week, I went 300 miles in two hours down the interstate. Good thing I didn't hit a rock on the road. Did I mention I cut off at least sixty people and caused three accidents in my wake?"
