ButtSPLOSION 

An event in which a very unlucky man or woman experiences such a case of explosive diherrieah that they have to hold on to something to fight liftoff. If the subject is a male and a bonerbo
then all this happens while he is blowing a full-on shed-full of baby-batter out of his jap's eye. EXTREMELY PAINFUL! If the sublect is a female then the(click me im funny!) poo will just explode with so much force that it sounds like a nuke going off in a monkey's stomach while he is riding a big-wheel to cancun to meet a brown eyed, homeless whoman who is jacking off some guy cause he gave her a box of fried chicken from KFC that was sold from some gawkey teenager who had terrable acne that even Proactive cant solve! see what im getting at?

Buttplosion 

When one attempts to release a short loud collection of methane gas, otherwise known as a fart, but releases a concentrated sphere of fecal matter into ones underwear. The collection of feces is usually leathery in texture, thus preventing excessive smearing, but it will stain.

The difference between a buttplosion and a shart is that it is more than possible for a shart to leak out quietly and discreetly. A buttplosion is incredibly sonorous, and cannot be done discreetly as it is a powerful, full-force anal gust that pushes the turd into the pants.

After a buttplosion it is imperative that the victim behave nonchalantly. It is a guarantee that the buttplosion was heard, but the crowd will only think the victim farted. Laugh at yourself, or pretend it wasn't you; but escape the premises as soon as possible, because the resulting anal waste will cause a foul odor to accumulate around the company you're keeping. Go to a safe and secure location, get some rubber gloves, and go through with the disgusting and sickening act of cleaning up the large bits of poop that has most assuredly spread copiously in your underwear. It is probably best that that the soiled underwear be permanently discarded after the incident, for there will undoubtedly be stains.

-Did you see Bill run out of here, what was that about?

-He farted and I think it was a buttplosion. He seemed pretty worried and scared.

-Poor bastard.

The aftermath of cumming so hard, you rid your face of all that heinous acne.

That bustplosion really helped me clear my face before picture day.

bumsplosion

The blast of diarrhea that occurs when one has been traveling in developing countries. The detonation is usually preceded by a series of tremors indicating the bumsplosion is imminent and it is time to run toward the closest safe blast zone. The bumsplosion can happen anywhere, however, and unless one has made it to a safe blast zone, they usually find themselves laying on their sides at the site of the bumsplosion for the aftershocks.

I tripped on a little girl while running down the beach, feeling the tremors, and I found myself on my side at the epicenter of the bumsplosion, my head on a sandcastle.
