This is the guy that Chick Fil A serves on Sundays, told Katy Perry she’s just a plastic bag, and this guy probably 69s while being on top. If you see “that guy” you’re best move is probably just letting him cut you in line and hoping he remembers you one day.

That guy is one who attends a party only to take advantage someone's drunk girlfriend. Now not only did you ruin her life, but you also pissed off her boyfriend likewise all for your own greed. Perhaps this can be a tactic for vengeance, perhaps you are just a douchebag. Whatever the case, you are now "that guy"
Hungover college student: OMG OMG OMG, I totally shouldn't have slept with "that guy" last night! What if my boyfriend finds out? He'll probably beat me and none of it was even my fault!
Friend: About that... he was also at the party.
Hungover college student: O_O
