Kenji is such a riceball. He screams like a little girl, and he dropped wrestling for swing dance class because he's scared of getting beat. His old man probably isn't too pleased.

A derrogatory term against asians. I guess can be racist. I myself am asian, so i think its really funny, but if you are against racism, don't call asians it. About equal with the term "chink"
