top shelf

When one takes a crap in the water tank of a toilet. This is usually done as a party prank or as a method of smiting one's enemies. It's a real pain to clean out, stinks like hell, and makes the toilet flush brown for days.

That guy wouldn't give me a beer at the party at his house last night, so I gave him a top shelf.

ass shelf

Part of a woman's body just below the small of the back that curves out to form the top of her ass.

I ran my hand down her back and rested it upon her large ass shelf.

expect not to be there anymore. (Ex: discontinued items not taken off shelf yet)

"Bro, I had to do some serious shelf diving to find this box of cheese flavored Maruchans!"

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 Interest

When the types of books on someone’s bookshelves arguably gives a good insight of their personality, character, or (hidden) identity.

Jack’s shelf interest focuses on true crime books. What are the odds that he’d be a potential serial killer waiting to strike?

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.
