Dueling Harmonica 

Two individuals, undefined in orientation and/or gender, each partaking of one half of a mans penis, divided lengthwise, by means of oral suction.

After a heated arguement, they decide to compromise and perform the dueling harmonica.

Guy 1: Yo, these two babes shared my donicker last night.
Guy. 2: You mean they gave you a dueling harmonic?
Guy 1: Yeah, I guess.

dudding

The semi-professional art of doing of nothing productive. Apparel may include "dudding trousers" (pyjama bottoms) and a "dudding cave" (bedroom). Large amounts of comfort and food are a priority, while physical exertion is frowned upon.
It is particularly prevalent when hung over or on sick days, and often features long hours of television, films, computer games and/or masturbation.

"I dudded around in the living room playing Champ Manager for 10 hours while watching cricket, eating bacon and drinking milk."
"That's good dudding..."
"I know."

Dunderling

A term given to subordinates and followers of the real boss, esp. those who perform menial tasks with little responsibility because of diminished mental capacity.

Surprisingly, Karl Rove's dunderlings can be found in some of the highest places.

When you find more than one dunderhead underling in any organization, it's time to refer to them as Dunderlings.
