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!

Clenching

clench

adj. - When you have little time to do something; close; difficult.

Not to be confused with what you do to with your ass cheeks to prevent poop from involuntarily exiting.

"We have to be there in 5 minutes, it's gonna be pretty clench."

"I have all day surfing lessons for the next few weeks; my schedule is pretty clench right now."

"The exam had so much on it I barely finished. It was pretty clench."

Clenching

A neo-modern activity, involving the act of heterosexual men attending a homosexual nightclub with friends, traditionally for cheap drinks and the prospect of meeting an attractive woman with experimental tendencies. In doing this, the man often has to awkwardly reject the advances of drunk homosexual men, and hence 'clenching' their bumcheeks together.

Can be justified in conversation by shrugging shoulders and saying "YOLO."

"Hey, what are you doing tonight?"

"I'm going clenching with some friends"

"Ha, good luck.."
