McMooch 

A nick name for any of your Irish friends that have a "Mc" in the front on their name that are always mooching. Bumming cigarettes, beers, food, clothes and just about anything they can mooch. They will most often "forget" their wallet when eating out and have to borrow though never to pay back. They can however be very generous when money is available to them and blow through it immediately which is why they never have anything.

McMooch, I can't believe you forgot your wallet again and need to hold 10.

Mcbomba 

A word created by me, and nobody else. It doesn't have a definition, but it can be used, and it is used as a friendly replacement for offensive words in order not to offend anyone, since it isn't offensive.

You're a mcbomba.
Why are you being such an annoying little mcbomba??

McGomer 

the opposite of McGyver - an individual who is unable to figure out what to do, no matter how simple the challenge.

Michael is a genuine McGomer - he fucks up everything he touches. He spends more time thinking up excuses than he does working.
