Chi means a variety of things in different languages as stated here. In Jamaican it's basically the equivelant to the american term gay (can be used when not reffering to homosexuals, just in a derrogitory way). In spanish it reffers to breasts/tits, in this way it's used commonly among blacks and mexicans. In japanese, it's short for daddy (Chihayo).
