What is Being That Guy?
1.
The one person you know that, no matter how many people agree with something, whether it's a course of action or a simple fact, ALWAYS disagrees. Hence the name,"Everyone wants to go except THAT GUY". This is believed to be on purpose or out of sheer stupidity. After disagreeing the person will usually follow up with a statement that is completely wrong and untrue because he "read is somewhere" or someone completely unreliable told him.
Person 1: "Alright, it's time to party but we have nowhere to drink at!"
Person 2:"Wait, no one is going to be at Corey's house for two days. Corey let's go by your house."
Corey: "No."
Person 1: "Why?"
Corey: "Because."
Person 2: "Because why?"
Corey: "Because I said."
Person 1: "Corey, seriously, stop being that guy."
