look up any word, like rockabilly girl:
 
1.
Means ''I'm good for'' or ''I like'' or ''I want'', can be used broadly. But basically, has positive connotations. The word stems from the k-pop band SNSD (Girl's Generation) song ''Genie'' in which the lyrics, ''I'm genie for you boy'' appear.
Boy: I'm genie for you babe.

Girl 1: Where should we go for lunch?
Girl 2: I'm genie for some korean.
