Muddy Wheel barrow 

When you blow your load in someone’s ass hole and in an effort to save your sheet (or whatever your on) you grab your partner by the ankles and make them walk on their hands until you get to the bathroom (or a proper dumping area).

If it weren’t for the muddy wheel barrow I would have ruined my new sheets!

Mundacity 

An event or happening such as a conversation or movie that is so mind numbingly mundane that it is audacious in its attempt to bore you to death.

I sat in that lecture for 3 hours, the mundacity of it all was excruciating.

It’s the mundacity of Napoleon Dynamite that makes it so funny.

Mundhir 

Great friend, Really good looking, great body! someone that really knows how to have a good time. Crazy motherfucker who does extremely stupid shit at times, like kicking a wall, ramming face first into objects etc..

Procastinator, highly intelligent, very funny, but even when doing something stupid they can make it look extremely cool, or just utterly hilarious. More or less very popular...And a complete slag

Is she making out with Mundhir, arrrrgh he's such a slut!

Anthony Mundine 

A famous boxer from Australia.
Unless you are reaching the end of your career/tether as a boxer, you wont have much chance of facing him. As he only likes to do mismatches, and fight people way beneath him.
In one such mismatch, he fought a Panamanian. At the time, "The Man" was ranked number 4 in the world, while his Panamanian opponent was at number 200 or so. Which creates a mixed idea of a man, who is at the top of his game, but fights weaklings, who are beneath him, for some cheap thrills.

The day that Anthony Mundine fights Danny Green, is the day that you see me as a happy man.
