Feesneeze 

Sneezing, while sitting on the toilet, with half a turd already hanging out of your ass.

I was halfway finished with a slow, peaceful slam in stall #3, when all of the sudden I feesneezed and the brown torpedo was fired rather quickly.

Fecesneeze 

A strong wet sneeze that occurs at both ends simultaneously.

For thousands of years, men abruptly shit themselves, but had no appropriate term to define the event.

Now, with the coining of the term in 2012 by Ben Grunfeld from Melbourne, Australia, people around the world can declare with shaky pride, "Do you have any spare underdacks? I just Fecesneezed a hole through the ones I'm wearing..."

Pronounced: FeeSneeze - the c is silent.

Example:
"Excuse me madam, was that brown patch on the back of your dress caused by sitting in mud, or did you fecesneeze strongly?"

It is also acceptable to proclaim, "oh dang it, I just Fecesneezed myself again!""
