McBaining

When you are doing a chick doggie style in the cockpit of a jetplane and a fighter jet pulls up next to you demanding to know what you are doing and it's at that point that you cum so hard that your cum explodes through the chick's mouth, through the window (not shattering it) and then it goes through the fighter pilot's skull, killing him.

Christopher Walken: So I was totally McBaining this chick last night and its at that point I knew I had to go to Woodstock.

Me: That's the most amazing thing I've ever heard.

McGanning

To 'Mcgann' beers, or simply 'Mcganning', refers to the act of cracking open a can of beer taking a few sips and setting the can down or otherwise implying that it is finished with no less than a third of the can's contents remaining.
The act of Mcganning beers will typically consist of repetition of this behavior and may be accompanied by boasts of how many beers they have 'drank' so far.
Mcganning is generally frowned upon as it is not cost effective and leads to having to clean up wounded soldiers the next day.

1. "This keystone light wasn't cheap so I don't want to see any of you bastards Mcganning these beers"

2. "I haven't seen someone Mcgann beers like that since freshman year. who invited those slats to the party anyway?"

John McCaining

To have a very conservative strategy when playing Super Smash Brothers in hopes to just be the last man standing while accomplishing nothing during gameplay.

This usually includes avoiding contact with other players altogether while occasionally throwing projectiles or using an item. A person who was John McCaining will usually end the match with a win and only one K.O.

Generally, this will cause everybody to detect that said player is John McCaining and then focus solely on knocking them off for several seconds, creating an adverse effect.

This practice can often be detected by hearing a flood of "come on, step it up" and "you're too slow."

"I can't believe I'm already down to one life, I think I'll be John McCaining the rest of this one out."

McNairing 

When a man cheats on his mistress with another woman, the mistress (not the wife) has been McNaired.

Vickery's mistress flew into a wild rage upon learning that her lover, married as he was, was McNairing her with another, third woman.
