dumming out 

A term used in Connecticut for the dance that was made in the 860 area code, particularly Hartford. It involves imitation of common activities such as making a Rubix cube and shooting guns.

"Yooo you saw how he was freaking it at the party? I wish I could dum out like 860 heads."
"I'm a pro at dumming out, play some Gangstalicious for me."
"You cant dum right my guy, you're from 203."

or

"Do you know who plays drums for Slayer?"
"Yeah, Dave Lombardo. Why?"
"Well, let's keep it that way. Stop drummering. Douche."

Dumbening 

A rare, genetic condition found in males, usually surfacing at the on-set of puberty; the result of which is a swift plummeting of the carrier's overall intelligence.

Young Abraham quickly went from smart as a monkey to dumb as a chimp, as a result of his dumbening.

Dufnering

a posture position where some one sits on the floor slouching with their back against the wall, legs extended straight out, toes pointed skyward, arms down to the side, hands tucked underneath legs, while staring forward with a faraway gaze expression

After a long day on the golf course and a big bacon cheeseburger from Five Guys all I felt like doing was Dufnering out in front of the TV.
