upper decking 

The process of taking a shit in the tank of a toilet instead of the bowl so when the next person flushes, all the shit goes into the bowl

Taking a shit in the tank instead of the toliet is upper decking.

ducking 

occurs when abusing downers(opiates, benzos, ambien, etc...) one will fall asleep for a few seconds, sometimes even a few minutes, and wake back up as their head falls forward. this occurs over and over again resulting in the user looking as though their head is bobbing up and down. much like a ducks head bob's up and down outside the water as they look for food.

Look at Tia. she's ducking hard right now.

Man, I'm loaded, I cant stop ducking.

Upper Decking 

Deficating in the tank of someone's toilet, rather than the bowl. Often employed in malicious context.

Suzy could not figure out why her toiled would flush only brown water. Little did she know that Johnny had upper decked that bitch the previous night.

Dacking

(Australian slang) The act of pulling someone's pants or shorts down when they least suspect it, usually by sneaking up behind. Intended to cause maximum embarrassment, particularly if the "double dacking" is deployed, which also removes the underwear, exposing genitals.

A typical form of humiliation or payback in school yards in Australia.

Young Steve was talking with a group of sheilas he wouldn't mind having a crack at one day.

Suddenly, Dave emerges from behind and gives Steve a dacking.

Steve: Oi fkn *frantically grabs at pants*
Dave: GUEHEHHEHE
Girls: *titter*
