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.

bun season

Lasting from November to about April...bun season is the time of year that people spend indoors with a mate. This mate may or may not last thru all of bun season, or even into the spring/summer months when most teens go back to hugging the block.This often results in broken hearts, hurt feelings and bitter exes. Due to the fact that females dont wear a lot of clothes during the spring/summer...niggas start showing they asses.

Its bun season bitch.

bread-bun sandwich

1. A crudely split sandwich into two pieces and one piece gets more filling.
2. Two slices of bread not contain enough filling between them.
3. Two bread slices that are so thick in size that it dwarfs the filling.

Loser guy say’s "Hey, my half of the sandwich we split has no steak!" "Looks like you just got a bread-bun sandwich.” Said the other guy and laughs.

specialized bun steamer 

When you can feel someone’s breath on your asscheeks. And you’re paying them for it.

Like when you’re polishing an apple, but it’s your buttcheeks.

“He was a real specialized bun steamer.”
