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"
"Oh man I have a Butt Bubble!"
"Damn man thats disgusting!!"
"OH GOD ITS JUST SITTING THERE!"
"OH MAN OH MAN OH MAN"
"Damn man thats disgusting!!"
"OH GOD ITS JUST SITTING THERE!"
"OH MAN OH MAN OH MAN"
