The art of projectile-style defecation. The end result is a messy, steamy, smelly possible smoke filled (we don't get it either) bathroom who's cleaning requires at least a firehose and a bucket of bleach.
Assplosions have been known to inexplicably end up on the underside of the toilet seat.
In ancient China, those capable of the assplosion were looked upon with the highest regard.
An ejaculatory bomb reaching speeds of at least Mach-2 and usually involving no less than 6 ounces of fluid. A true "rocket" travels at thrice (or more) the distance of ones normal load and has been known to target the eyeball, inner ear and ceiling. The rocket can be measured by torso length and/or mouthfull.
Oh snap, my jizz rocket shot 4-torsos; thats a new Personal Best!
A disgusting assplosion of fecal matter (all forms) occuring whilst still wearing pants. 97% of the time the "Blowout" comes without warning; the proverbial brown-tsunami has been known to hit no matter the situation.
Only three people have died from Blowouts in the past 37 years.
intercom at retirement home: "Would Oscar please report to ward 6 with a bucket of bleach and a tire iron, Beatrice had another BM Blowout."
