ButtSlap

When something is underwhelming or disappointing. Most often used in a context that involves a person describing the poor state of something, such as a meal or TV show.

"Dude, this caf food is straight buttslap." "I'm bummed bro, that movie was buttslap."

buttflap 

Those goofy squares of cloth, sometimes cut from an old tshirt or some other random piece of cloth (but now available at hot topic probably) that alot of street punks wear dangling from the back of their pants.

Freddie had to lift his buttflap out of the way to get his H out of his back pocket.

Buttcape 

A cape or cloth covering the rear end of a man or woman. If there is cloth on either or both sides of the hips, it would not be considered a butt cape, but a skirt with half of it cut off or just a plain old skirt.

Chun Li from Street Fighter really owns that buttcape look! Good for her!
