jiggle pants 

Flared pants.
Pants that give unnatural amount of ass jiggle no matter how skinny you are.

Todd: Damn girl, your ass jiggling everywhere with those jiggle pants
David: goddammit todd, stop looking at my ass!

Black Jiggle Pants 

Tight black stretchy pants usually worn with no underwear that emphasize the buttocks by tightly hugging it yet still allowing it to jiggle when walking. When worn by the wrong individual the results can be devastating. Also known as yoga pants.

Look at Robyn's butt in those black jiggle pants, it makes me want to giggle and dance.
