assblast

A loud, odiferous, noxious, and entirely pleasing emission of gases and various chemicals and excreta from one's nether gate.

I gave a satisfying assblast in the crowded elevator and caused a panic between floors 11 and 14.

Get the Ass Blaster mug.

When you are having a loud, explosive diarrhea; and you are powering up like a Super Saiyan - tensing your muscles, fists clenched and yelling with intensity.

Note: more satisfying when someone hears it; them looking at you in disbelief is considered a bonus

I was in the bathroom and heard what sounded like an ass blaster disaster. It was like his power level was over 9000!
