the basic definition for being "that guy" is to just be as annoying as humanly possible at any and all types of social functions, and annoying in many different ways,
examples can include drinking too much and pissing your pants/vomiting, hitting on girls that are most def not interested in you, telling ridiculous stories that are
obvious lies, and many other crazy ridiculous things. You most definitely do not want to become "that guy".
Guy 1: Not bad in here tonight (in a bar/club).
Guy 2: Yeh, good amount of women in here, and the drink specials actually drinks we can enjoy.
Guy 3: Dude I def have my eyes on that hottie over there (points)
"That Guy": Yo, wazzup guys (annoying prolonged wazzup) this is my 4th shot and I already had 5 beers also!
Guy 1: Wow I dont care how much I have to drink, why would I care about how much you have??
Guy 2: Yeh you really are "That guy".
Guy 1 & 3: Yeh seriously, get lost you loser.
"That Guy": Sorry guys, I wont bother you again.

"That Guy": (Shouting as loud as he can to be heard over music at house party) Alright I am leaving to go to (insert crappy bar name here)!
Rest of Party: Alright later, (thinking thank the good lord he is leaving)
"That Guy": (Still shouting but music shuts off to start another song) Gonna try and get laid !!
Rest of Party: HAHAHAHA, yeh good luck man, LOSER!
"That Guy": (out in his car thinking) Wow, I really am that guy.

A man who exhibits characteristics of a traditional male role model. He is likely knowledgeable in a wide variety of practical skills. He tends to be modest and friendly, helping others freely, but exudes confidence. Others may look up to him and seek him out for help or advice.
Not only does he grill a mean steak, but at his barbeque last week he figured out a problem with my car that's baffled me for weeks! It seems like he knows what he's doing with everything, He's a real guy's guy.

A popular game in the Midwest, East Coast and California Bay Area. The first player says something, and the other players respond to whether it is "Guys" or "Not Guys."
Guys or Not Guys is not only a great American past time, but it is fun for all ages.

ChoreBoy asked Finch whether he thought his buttix looked Guys or Not Guys. Finch stated "Not Guys!" because he saw absolutely no smears of stool on his cheeks.

"Peking Duck, Guys or Not Guys?" Guys! Pustifer responded.

1. When two or more guys kiss and make out and get off together. A quick kiss or grope doesn't count. Extended tongue action and fondling are required for an act to be guy on guy. Most of the time this ends when they wank each other until they come (because guys are good at wanking). Guys who are more familiar with each other, or kinky, will 69 and suck cock and rim and have butt sex.

2. Porn for girls. The type of porn in which all participants are hot and generally getting off on the proceedings. Participating in a guy on guy moment is the number one female fantasy.
Julie: Did you get that Mad TV guy on guy youtube clip that I sent you?
Jodie: Omg that was so hot, do you think that all guys really do that?

A Guy Guy is usually an immature male who is obsessed with the college life. They do not live near beach towns, but during the summer that's where they can be found. They can be seen usually on 32nd street in Longport NJ in their Old Navy flowered board shorts, a white wife beater tank top, addidas flip flops(sometimes with socks), a puka shell necklass tight around their neck, usually sporting an upside down visor and spiked or gelled and high lighted hair. They can be heard talking to their Guy Guy friends about frats, college parties and girls. They usually spend their time tossing a foot ball around between themselves or strollng the shore line looking for women. They are insecure and gay and are having a hard time hiding it.
The Guy Guy's were flocking to the beach today, they all had their fresh Old Navy flowered boardshorts on.
