Get a that guy mug for your mate Yasemin.
Someone who's always calling a girl, or IM-ing her, or running into her at a bar. He always flirts with her -- and even thinks he has a shot -- even though she's made it perfectly clear that she's not interested. Not as malicious as a stalker, just annoying.
Ugh, that guy called me AGAIN.

That Guy is the baddest motherfucker on this earth, you can usually hear about him in tv shows when the main characters are jealous because "That Guy's getting laid by those two gals tonight" or "That Guy actually bought Playboy Mansion".

An easy mistake to make is hear about "that guy" and believe people are referring to "That Guy". The two are polar opposites, one being the pinnacle of awesome and the other being a retarded pussy that frequent parties orchestrated by 15 year olds.

While That Guy is pretty cool, he's also an elitist asshole, so you're probably not his friend unless you're easy and pretty hot, in which case you're not reading this.
-"That Guy just made it with her"
-"What? But she's my (trophy) wife!"
-"Apparently That Guy doesn't care much for the bonds of marriage"
-"Neither do I but I'm an old rich man!"
-"I hear your wife's on redtube now"

That Guy taking from the rich and giving back to the poor.
