Clenchy

Clenching Chowder 

What happens after having unprotected anal intercourse with a man with a tiny penis. The ejaculate doesn't get past the Anus Hotel lobby (so to speak) and coagulates very close to the one and only exit; occasionally causing a bloated feeling or general lower GI discomfort.

After they found him half naked with his scout master in the closet, he ran to that restroom so fast you just knew he was clenching chowder.

The Clench 

Jaw clenching caused as a side-effect of consuming LSD. Generally not dangerous. Treated by staying hydrated and exercising the mouth. Nothing to worry about as worrying can cause a bad trip.

Luke: You just gotta watch out for The Clench
A.J. (On LSD): The Clench? Wtf is that?
Luke: You don't know about The Clench man? That shit will lock your mouth shut!
