A boy from a Korean origin...

Either born in Korea or has parents from Korea.

Generally smart, usually overlooked in terms of attractivness (but they are attractive!), shy, and (probably) the best looking guys from East Asia.

Korean boy wasted is a level of drunkenness superior to all others. When this drunk, even Snooki would say "You're too drunk", though she'll likely smoosh you anyway. Be prepared to wake up naked in a ditch with a mannequin, a half-stick of butter, a Burt Reynolds autographed glow in the dark snorkel and no recollection of how this ridiculous assortment of items came to be in your possession.
Taylor: I'm getting soooo whitegirl wasted tonight!
Mike: Eh, that sounds okay but I'd rather get Korean boy wasted. Nobody goes harder than they do. When they get hungover they're not just ill, they're Kim Jong-il.

Much like his ancestral counterpart (see "Jam Boy"), a Korean Jam Boy is the act of smearing kimchi pepper paste on the face of a small weak korean man/boy to attract the mosquitoes while you troll through Seoul looking for side-ways vagina to slay. The size of the Korean Jam Boy is insignificant since every Korean man can be physically dominated by any other race. If the pepper paste runs into his eyes you can piss on his face, because if he starts to cry from the burning you will have to kill him and throw in a dumpster and then get a new one. The night usually concludes with banging his sister while you make him videotape and beat off in the corner, after which you allow him to wash the kimchi pepper paste off his face while his sister folds your laundry and cooks you Korean BBQ. Before you kick them out you take all of their money so they have to walk home.
Friend: "Dude your Korean Jam Boy is fucked up."

Me: "I know, I had to break both of his arms because he was eating all of the kimchi on his face"
