McMurdo 

A sexually frigged woman or man.

Derives from the McMurdo Dry Valleys of Antarctica, the coldest and one of world's most extreme deserts, which has been ice-free for thousands of years.

Perhaps you should move on to more fertile territory, bro. McMurdo over there will only frustrate you.

McMurdo muzzle loader 

When you grab a 2 liter of mountain dew, put in your fat girlfriends asshole and empty it in there. Then you tongue punch her fart box and drink the dew out the booty hole.

Gave my lady a McMurdo muzzle loader last night, she said it was the best time of her life!

Mcmurder 

Vehicular homicide linked to McDonalds. People focused on drowning their fat asses in lipids will often ignore basic traffic laws, racing to the scene of the nearest McDonalds, leaving a path of destruction in their wake.

Additionally, even after sating their burger lust, these Mcmurderers may often be too busy wolfing down fries to take notice of their surroundings, making them disproportionately likely to cause an accident.

Steering wheel slippage due to greasy fry fingers may also be a possibility.

My friend was Mcmurdered at that intersection when that hamburglar motherfucker ran him over.

McMurder 

The act of smashing a lot of McDonalds food. Originated in southeast MI where McDonalds are more common than Kanye West's TV outbursts, it's when you kill a value meal and go back for that 4 piece or double cheeseburger and feel like you just comitted a serious crime on there establishment. You die a little inside too and later you murder some porcelain

I'm going down to hit a McMurder session, you down?

McMurder 

One who would more then likely kill for a laugh. Likes to hit on people but not in the loving way. Makes fun of peoples defects and boasts about his own. Likely worked fast food for some years maybe a manager. Also likes long walks on the beach and rum and coke. Will more then likely share a cell with an axe murderer.

I saw McMurder and ran away crying.
