Taint Shelf

The tiny, almost useless, passenger accommodation on most modern sportsbikes. Often referred to as a “pillion”, this small, hard cushion has the effect of bludgeoning the area between the passenger’s genitals and anus throughout the ride. Because of its height relative to the driver and generally awkward seating position, these seats have a reputation for deterring passengers from wanting to ride along. These seats are a characteristic of the split tail style of motorcycles, opposed to the conventional “banana” seat (single piece) design. The prevalence of this pragmatically useless design can be attributed to the greatly improved aesthetics and improved control of the motorcycle while in full tuck, as the driver can scoot back into the shelf to secure themselves from sliding further rearward.

“Dude, do you remember having to ride bitch on my Zx10r?”
“Yeah bra, my ass still huts from that retarded taint shelf…”

shelf park

(verb) To shelf park is to perform the practice of placing a space-consuming item (usually one that can be situated there for a justifiably significant amount of time such as a jug of milk or a box of beer) on a refrigerator shelf for the purpose of securing capacity for a potential future space-consuming food product to occupy.

nut shelf

a small, but sturdy peice of flat material (usually wood or plastic) that when attatched to the user's inner thigh creates a wonderful area in which to rest his nuts

Maurice got hit in the balls by a savage ape child so now he wears his nut shelf for support.

shelf butt

A large butt on an otherwise not large woman. So oddly large that it protrudes like a shelf.

If you just saw Jane from the waist up, you'd never guess how big her ass is ... what a shelf butt!
