look up any word, like hipster:
 
1.
A Korean slut who acts like a twinky, has the shittest memory and likes leather jackets. Jinwook's often suck at continuing conversations and are also inner camwhores. They are also carriers of herpes.
Girl 1: oh shit damn that's the hottest asian i've ever seen

Girl 2: yeah but he's a jinwook, don't want your vagina touching that

A Sexual position in which a male lies face down, another is inserting his dick into the other guys anal hole and a third guy is actually underneath the first guy sucking his dick. A fourth man is also optional, to put his dick in the second guys mouth.

A Jinwook (or a kimjin) is tan, mus-culy, and just plain sexy. but he also gets six A's which just ruins it. If the brother toned his academics down a little bit, the chicks will come running. but till then, expect some reaaalll lonelyness coming ur ways. its never good to overachieve.
girl 1: that guy is such a Jinwook
girl 2: what a shame, id totally bang him
