dijeridouchebag 

A general negativism created by combining the Australian aborigine instrument, the dijeridoo, and the negativism douchebag into a portmanteau.

This can be used on people of any origin, not just restricted to Australians or those of Australian descent.

Dude: That guy just cut me off!
Dude's friend: I saw that. What a dijeridouchbag.

-OR-

Dude: Excuse me, my battery's dead. I've got the jumper cables, but I need someone to jump me. Could you give me a jump?

Douchebag: I sure could...but I won't.

Dude: Wow...you're a dijeridouchebag.

Didgeridouchebag 

A person who tells you that they bought you an awesome Christmas present from Australia but it doesn't come in the mail before you have to leave town so they promise they will send it to you, but then they never do, even though there is a post office in the building that they work in. Then they just make you more curious about what it could be by listing things that are Australian and telling you it could be one of those things. For example, a didgeridoo, Men At Work, cane toads, Outback Steakhouse, etc.

Kurt is a didgeridouchebag because it is February and I still haven't gotten this supposedly great Christmas present from Australia that he claims to have gotten me.
