That One Guy 

We all know him...

Person 1: Oh! You know who I saw today? It was... ummm... what's his name... you know, that one guy?
Person 2: Oh, yeah. Him.

That One Guy 

A person who stands out above everyone else, usually in a sarcastically negative way.

Timmy wanted to be That One Guy and decided to smash his friend's face into the cake. Hey, if he wasn't gonna do it, someone else was gonna do it. Let's be honest, it's inevitable.

That one guy 

You ever go back and help that guy that you dispassionately waved off the stage or no? Did he kill himself? Do you know? I don't know his name.

That one guy "Daddy Jesus! I need help! Lay your hands upon me!"

Hym "HAHAHAHAHA! That is so fucking embarrassing for you! First of all, even asking for help makes you pathetic. Secondly, you cannot afford him you idiot! Third, you look like a crazy sycophantic weirdo! Hahahahahaaa!!!"

That One Guy 

That one person who genuinely nobody likes for a certain reason. Everybody knows who you are talking about as soon as you say this.

“That One Guy just asked the teacher about the homework and she forgot about it until he told her.”
“What a dick, that’s the reason nobody fucking likes him.”
