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.”

That One Guy With the Stuff 

He's that one guy that you know, and that everyone else knows, but you don't know his name. You do know that he's that guy, not the other guy, but that one guy, you know, the one with the stuff in the thing. He also has some hair and that one thing where he goes places a lot of the time sometimes.

Tyler: Do you have the notes?
Zane: No, that one guy does.
Tyler: Which guy?
Zane: You know, that one guy with the stuff, and he has that thing with the stuff in it, not the other guy, the one who has that thing where he goes places. Do you know who I'm talking about?
Tyler: Yeah, you mean that one guy with the thing where he has hair and stuff right? I know who it is, thanks.

That One Guy's Girlfriend 

The name given to girls that aren't popular but have boyfriends that are sort of known by everyone.

"Dude, who's that? I haven't seen her like... EVER. Where the hell did she come from?"
"I think that's That One Guy's Girlfriend, you know, the one that looks like Harry Potter? She's been in the same school as you since 3rd grade, man. Seven whole years."
"No fucking way... Huh..."
And they both continue on their way, only to forget about her.

That one guy in the corner of the class 

Hes just that guy in t he corner eating chips with head phones or smth listening to music and completely ignoring anything the teacher is saying, even if the entire class is staring at him.
Luckily, that guy could be any thing, be it A joe, mia, yunus or a random dark evil sorcerer that can some bunnies and giant carnivorous turtles

Look, its That one guy in the corner of the class

Hmm

He seems to also be a evil sorcerer, considering how there a giant turtle next to him
