The best thing in the entire world. You eat this delicious sandwich, large with a coke. It's the best feeling in the entire world. Indescribable.
Alysa and I went and ate a delicious Big Mac yesterday.

I am so happy because of the Big Mac-ing we just did.

Leading to it sliding apart and making a mess.
Customer 1: I got myself a Big Mac, and I swear the bottom piece of bread disappeared..

Customer 2: Dude, it's the Big Mac Effect.

Customer 1: Damn it, now it's fucking everywhere..

The fear of having a Big Mac attack and not being able to sexually satisfy the Big Mac. So you wonder if there is even any point in puting a condem on if the Big Mac is just going to lay there like a dead fish. I mean come on, where both adults here, if you don't want to be here then we should just call it off right now.....
I Love you Big Mac.

A joke made by Rooster Teeth in the Rooster Teeth Podcast #201.
It comes from a story Burnie Burns (the co-founder of Rooster Teeth) told about Daniel Gruchy (a friend of Rooster Teeth and fellow Youtuber) getting confused about the McDonald's menu, as he thought they read left to right instead of top to bottom, ending with the result "Big Mac Chicken Legend Sundae".
McDonald's Employee: Welcome to McDonald's, what do you want?
Dan: Um...I'll have a...um...
McDonald's Employee: We need you to respond sir, you're holding up the line.
Dan: Fine, I'll have a Big Mac Chicken Legend Sundae.
McDonald's Employee: Excuse me?
Dan: What, are they sold out or something?
McDonald's Employee: I'm sorry, I just...just pick something else.
Dan: How about a Chicken Nugget Sausage McMuffin Coca-Cola.
Gavin, who has been standing behind Dan this entire time, calls Dan a "fucking idiot", turns around, and walks away.
