뭘봐 =/= Close Ur Mouth. 뭘봐 = What are you looking at? 봐 is a rude-ish way of saying look, while 뭘 is a contraction that means what. Kind of like in English we say don’t for do not, that’s what 뭘 is. The English title is appropriate for the content of the song, however, please know that it is not a translation.
