Bumchicker 

A word to describe when someone is being a party pooper, a downer, or joy kill.

It was clear to me as Jacob moped into the door, that he was being a bumchicker, as he through a pitty party about having to go to work.

Bumcrack 

An inch long crevice found on the derriere, that has escaped the modest covering from trousers.

"Cor, look at her bumcrack, the dirty slapper! You could park a car in that!"

East Bumcrack University 

A marginal research university that publishes man-made climate change denial research that is unsupported by mainstream institutions.

First used by Australian journalist Annabel Crabb on ABC's "Insiders" program in response to climate skeptic Andrew Bolt. Quoted in Hansard minutes of Australian Senate, Nov 2009.

That sounds like another factoid you picked from East Bumcrack University to support your climate change skeptic arguments

buttcracker 

A person who is very proficient in the art of the deadly fart, it may be silent, it may be noisy, but one always knows for a fact that it will be stinky, it will clear the room, and sicken the occupants with it's ghastly odor, this term was coined by the fact that some of these odoious folk have actually cracked the skin around the butthole by releasing their poisonous gas.

OMG!That Buttcracker left an odor so bad we had to air out the place for three days!!!!!
