An experience when you fart and the fart gasses get trapped between your cheeks causing a bubble sensation, that will either raise up your crack or sink between your legs making you press your arse cheeks together in an attempt to "pop it"

The result of a butt that is too small for a pair of jeans and leaves a bubble of nothing because one's butt isn't filling up the space.
My butt is so flat! I can't even wear jeans without having a butt bubble!
