bun duster 

A piker who frequents teas, dinners ans other entertainments but makes no attempts to repay his social obligations.

Under-bun Syndrome 

The phenomenon where the bottom bun of a burger mysteriously disappears faster than the top bun. The eater's thumbs are precariously placed on a postage-stamp sized "under-bun", while the top bun is still the same size as the burger.

Your thumbs are covered with ketchup because you've got a bad case of under-bun syndrome.

Stink Bun 

The messy ponytail or bun on top of a woman's head most commonly worn by Britney Spears in tabloid magazine photos.
May look like a hair-pineapple on the crown of the head fashioned crudely with an old scrunchie or even a pen.

"Look at her Stink Bun, her hair looks like it smells!"
