A secret Menu item. When you go to McDonald's and your choice of a secret menu item is to order a Hamburger and put fries in it. Whereas all your friends are ordering the bigger and more inventive secret menu items such as the McGangBang.
The term was first coined by Geovanna Antoinette Kwan, as can be seen in her YouTube video titled 'A McGangBang' uploaded on May 3rd 2011.
Geo:'So that's how you make a McGangBang now I'm gonna show you a McGay. A McGay is gonna be demonstrated by our very own Joe. Joe can you demonstrate the McGay?
Joe: A McGay - Geo made up this name because it's so weeny - it's just fries in a hamburger. I dont care if you think it's gay because it's delicious to me.
1. A night where one drinks an insane amount of alcohol and will eventually pass out. Can be paired with Mega to make a Mega-McGarry night (for a night you will never remember and will probably end up in the hospital) or with Mini to make Mini-McGarry (for a night that you only get a little shit faced). Not to be used lightly.
Named for a certain Physics teacher who enjoys mean Manhattans and keeps a fridge in her room for "experiments" with ethanol. She also failed a Physics lab in college to go to happy hour.
Named in honor of a special uber geay McGarrett. In general, refers to the guy that absolutely repels women. He is not a man's man. He is not even a fag hag. Kinda resembles smegma. Is known to kill a party within mere moments. Just walk away. Also tends to look like a cartoon character.
