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.."

penis clenching

when one sees someone so un-sexually arousing that the tip of the penis literally clenches shut. One assumes this is a natural human reaction to even the slightest chance of sperm leaving the body and finding its way to an egg housed in the object of one's disgust, thus furthering the insult to mankind that is said person.

Guy 1: "dude, that look on your face, are you penis clenching?"
Guy 2: "Check out Nora the whale over by the concessions stand" (shocker)

Clenching the Wrench

When you aggressively stroke your cock so hard you shit yourself. This may cause small lacerations along the shaft/tip, and or severe fright from masturbation.

Friend: "Is Tommy here?"
Mom: "Yes, he's upstairs in his room"
Friend: "Okay" *goes to walk upstairs*
Mom: "I wouldn't go up there unless you want to watch/hear him clenching the wrench. He's been doing it all week."

Ass-Clenching Cold

A state when the temperature is so low, that in addition to you shivering and rubbing your arms, your ass cheeks press together in order to prevent a heat loss from your buttocks.

You'll freeze to death if you go out in that Ass-Clenching Cold Weather!
