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.
