Combluotion. 

Calm Blue Ocean, when chanted, takes on the form of an entirely different word. Combluotion can be said in place of Calm Blue Ocean, even though the difference is very small.

"Okay, relax... think positive... Combluotion... Combluotion... Combluotion..."

Anal Combustion

Any form of explosion just inside the anus. Could be the result of inserting and igniting gasoline or gunpowder, attempting to light a fart, or that Mexican food from yesterday. Depending on the strength of the sphincter, severe anal combustion may result in blowing out the anal socket or rupturing of the rectum.

I had pretty bad anal combustion after that spicy 15 bean soup--it almost blew out my sphincter!
