A massive expulsion of flatulence from the ass that originates deep within the bowels. It’s loud, lasts at least 5 seconds or longer and may or may not be putrid in odor. You feel like a new person upon release.
I left the classroom to release an ass cleanser in the hall.

I thought I was going to explode in that meeting. I let loose with an ass cleanser as soon as we took a break.

Brrrrrraaaaaaaaaappppppp!!!!!! Dude WTF was that sound? Just ripped an ass cleanser braaaaaahhhhh!
