YOU SAID:
Boy if you don’t shut your mouth I will shut it for you
INTO JAPANESE
Boy 口を閉じないなら私が口を閉じてあげるから
BACK INTO ENGLISH
Boy, if you don't shut your mouth, I'll do it for you
INTO JAPANESE
Boy 口を閉じないなら僕がやってあげるよ
BACK INTO ENGLISH
Boy, if you don't shut your mouth, I'll do it for you
That didn't even make that much sense in English.
