When you are sitting in class, and try to slowly let a fart out, but the fart concentrates into a bubble and slowly slides from your butthole across your taint and pops right before your balls.
I was taking a test in Mrs. Russels class, and i had to let one rip. I slowly let off a fart, but to my fears it became a massive taint bubble. luckily it popped without sound and the class was none the wiser.
