From a science fiction movie entitled The Mist (2007):
— Nobody else heard that sound?
— What sound?
— I don't know. Like a weird noise. Back there in the dark. Like something was, like, pressing against the door.
— Did you hear it before the lights went out or after?
— No, only after. But, look, I heard it, okay?
— Nobody's calling you a liar.
— That's what it sounds like.
— No, no, no, no. Now, don't be that away, Mr Drayton. You had a scare, no doubt. What say we all go check it out?
What does that exprssion exactly mean?
