A condition highly prevalent in the 1980's. Someone (typically a woman) wears pants that are pulled up above their navel, as was the style of the times. This, viewed from behind, results in the phenomenon known as "long butt" where a normal butt suddenly seems much longer than would be thought healthy.

When women wear tight jeans that press the fat in the bottom together and elongate up and down the butt.
