Translation:He wants to talk with you about your girlfriend.
from "koro" (heart) and "amiko" (friend). Slap them bad boys together and you get "koramik(in)o" lit. heart friend aka boyfriend/girlfriend.
(plus "kora" can mean heart in an adverbial sense. So, I guess it could be "kora" + "amiko" lit. a heart friend. So maybe this is a better etymology?)
