Donking 

Drinking liquor.

This term was accidentally created early September 2011 as a result of a typo. Started spreading slowly through Twitter since.

It's funny cause when making sentences, it sounds like it would be an innuendo, but it really isn't.

Donking = Drinking.

I donked with a group of buddies last week.
I saw you donking with your boyfriend.
You donk too much. Donker.

Skull Ducking 

Skull ducking is an ancient myan sport which involves tapping someone on the skull with the bill of a duck. Whoever can withstand being ducked for the longest time win. Although it is quite complicated and it involves the flexing of certain skeletal muscles to make the skull ducking last longer.

Recently, has been recommended by some that it should be an olympic sport.

We skull ducked for hours.
I Skull ducked your grandmother.
I dipped the remainder of my penis in a shit covered, hairy bloody, egg smelling, tuna infested, bubbling, vaginal puss farting hole after we were done Skull Ducking Your grandmother.

dicking around 

Sitting upon ones arse, wasting time.

A free thinking, free spirited form of entertainment.

Time spent unwisely due to the lack of enough intelligence to complete a moderately complicated task.

"I was dicking around all day.."
