When an article of your clothing gets stuck between your butt cheeks. Separate from a wegdie because the clothing is not going up your butt, it just gets smashed a little between your cheeks. Common with dresses and right when you stand up after sitting for a while.
When you first get out of the water and your bikini bottoms ride up your butt is an example of suck butt
