I'm from Turkey. I have a question about a sentence. I thought it is an idiom, but I can't find it in the idioms section. the sentence is: his mouth cut from the glass. the man who feels horror and fear.
I just wanna know the meaning of this 'his mouth cut from the glass' sentence.

Oh, so sorry. where was my mind? it is not an idiom. ok. I don't expect an answer anymore.
