ThatGuy 

An Overall average looking guy, that dresses simply with a boring personality that is dating the hottest girl in the room.

Bartender: Be Careful she's sitting with her boyfriend
Guy1: ThatGuy? She's Dating Him? Really? Ok

ThatGuy 

A common Indian Nigga that smells worse than my dead grandma everywhere he goes. If you come by this weak, fat, ugly, dumb, hairy sack of shit, search for a bunker immediately. Do not come out till you don't smell sweaty balls and curry anymore. The fat fuck will try calling you for your card number.

ThatGuy, Big talk with a small cock

oh my lord. this is a gamer tag of the most cracked Rainbow 6 player you've ever seen. he can hit a perfect headshot through a window from 40 meters away no scope. he could destroy any team he goes up against. he is the Aoi Todo of R6. he holds back each round so as not to kill the team every time. he lets his teammates get most of the kills sometimes because even though he is the unrecognized best player of Rainbow 6, he knows the world does not revolve around him. he likes to keep the match going. if you see him, just know. you have encountered a god among men. -ziptiedballs, his friend as personal r6 punching bag

This is a true ThatGuy_2119.

dude#1 "OH MY GOD. DUDE. I ENCOUNTERED THATGUY_2119 IN MY MATCH A SECOND AGO. HE HELD BACK UNTIL THE TOXIC 9 YEAR OLDS STARTED TALKING, THEN HE KILLED THEM ALL LIKE THE R6 JACK THE RIPPER.

dude#2: brother. you just encountered a legend. i hope you took a screenshot

I hate to be that guy, but... 

A phrase people can add before saying something nitpicky, like correcting you on some inconsequential fact.

Often secretly means, "I love to be that guy", since the kind of people who say it get a little thrill from correcting others and being pedantic.

"I hate to be that guy, but... you said The Matrix came out in April 1999. It was actually first released on March 31st."

Be that guy 

That sarcastic definition that surprisingly no one has made.

When you're doing something that's shitty or annoying as fuck and no one wants to stop you, because we live in 2021 and everyone is lazy.

Guy 1: *does something annoying over and over*
Guy 2: Be that guy...
Guy 1: *keeps doing it*
