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!

The Clench Instinct 

When a human dies, their final instinct is to clench their lower orifices. This is why Necrophiliacs claim that corpses are better than the real thing.

Human 1: Dude you see that girl when she was almost stabbed.
Human 2: Yeah, you could see the clench instinct kick in.
Human 1: Yeah dude, it was hot.

Stephen Hawking: My best discovery for science was and will always be, the clench instinct.

The Jaw Clench 

One of the sexiest things you could notice on a guy. When a guy clenches his jaw. It's not obvious. I just can't really explain it. It's just Really freaking hot.

The Italian Clench 

The Italian Clench - Imagine missionary sex, but instead of locking eyes, the male counterpart locks their legs and arms firmly around their partner, creating an Italian Clench. In order to complete the Italian Clench, the partner on top must wrap all extremities around their partner to create a pretzel like formation, all the while, thrusting only with their hips.

Carmela: How was your date with Chad last night?
Meadow: It was great, we got drinks and afterwards we went back to his apartment and he gave me the Italian Clench.
Carmela: Oh he's Italian?! That's so great you're dating someone from the old country.
Meadow: Yeah, but the whole time I was getting Italian Clenched he whispered "gabba goo" in my ear...

Ethan: Dude, did you end up getting laid last night? We lost track of you after we slammed those jager bombs with that girl you were on a date with.
Chad: Oh yeah, we went back to my place and I gave her the Italian Clench.

clench of the dragonfly 

A for profit clench/schism/subsect of the Church of the Subgenius, with a specific intent to buy out J.R. "Bob" Dobbs, own and dominate, the Church of the Subgenius.

A fraternal club of freaks, weirdos, and other unusual creatures.

Your grounded for going to that "Clench of the Dragonfly" cult meeting.

Joining the "Clench of the Dragonfly" is the stupidest idea ever.

Those greedy bastards at "Clench of the Dragonfly" will never raise the 5.5 billion dollars needed to buy out "Bob"
