Spontaneous Liquidation

When a person, place or thing, unexpectedly dissolves into a puddle of liquid. Sometimes bursting like a water balloon or melting into a puddle, most likely killing them. Direct opposite of spontaneous combustion.

In the first X-men movie, the character Senator Kelly died by Spontaneous Liquidation.
Or
I was watching two men climb down a ladder when suddenly the first man ignited in spontaneous combustion, luckily at the same time the man man burst in spontaneous liquidation, putting the flames out.

Shit Swamp

A common form of diarrhea, in which soft fecal matter and non digested food (most often lettuce or vegetables) covers much of the toilet's surface water, giving the appearance of a miniaturized marsh, swamp or bog within the bowl. It must then be allowed to linger; no flushing, until potency has been acquired and a second party has declared it to be such.

Also sometimes but rarely known as Bowel Bog

Alex is being a dick, I'm gonna go Shit Swamp his toilet. Wait 15 minutes and then go declare it.
or
If I find out which of you assholes just laid a Shit Swamp in my bathroom, I'll beat your nads in!

Never mind he declared it for you.
