tug-o-war with the Cyclops

Stroke the Salami
a date with Pam and her five friends
the five finger knuckle shuffle on the one-eyed, blue-veined, purple-headed, custard-chucking, salty yogurt slinger.

"Failing to find someone to fuck after the club, Jimmy resorted to a tug-o-war with the Cyclops."

Cycling

The lower intestinal cramping associated with diarrhea. The pain includes hot and cold flashes, goose bumps, and general irritation. Cycling refers to the way the pain comes on strong and then goes away repeatedly.

Dude, those Buffalo wings were good but I'm cycling big time. The bathroom here is disgusting so lets bounce, I need a decent toilet stat.

Citric Acid Cycle

A cellular process that occurs within the mitochondria within the cell. It begins with Acetyl CoA which is produced from a molecule of pyruvate which is produced by glycolysis. The pyruvate is then oxidized and releases a CO2 to the atmosphere. The pyruvate is then further oxidized when it reduces NAD to NADH. The pyruvate is now known as Acetate , Coenzyme A is then added to the Acetate making it highly unstable and rich in energy, ready for the Citric Acid Cycle. During the Citric Acid Cycle NADH and FADH2 is produced along with ATP form substrate-level phosphorylation and and a few molecules of GTP.

The Citric Acid Cycle is crucial to cellular respiration

Cyclops Tree

Eye Wood, or I would. A cyclops has an eye and a tree has wood. It is safe to say cyclops tree in public. It is the equivelent of saying I would smash (a girl or guy)

Cycasm

A portmanteau of the words "cyber" and "sarcasm" which defines those moments in which sarcasm is lost in virtual communication (instant messaging, Facebook messages, text messages, etc) due to the inability of giving the subtle tonal indication with one's voice about whether or not a statement is serious.

Variations:

Someone who is "cycastic" takes advantage of this weakness by stating things that could be construed either as truthful or sarcastic, usually as a way of being tentative in their conversations if they are shy, but also occasionally to purposely mess with a person's mind.

When cycasm has created an intellectual chasm, in which one of the persons involved in virtual conversation is on the opposite side of the sarcastic genius, the word "cychasm" can be used as a variation to simple cycasm.

Johnny: "I totally bombed that presentation today."
Mark: "Really? I thought it was sick!"
Johnny: "Is that cycasm?"
Mark: "No catching you in the cychasm."
Johnny: "You're too cycastic for your own good."
