The noise that some people make when they become agitated or troubled. Commonly preceeded by "mrrooraw" util the climax of the anger is reached and the person breaks into an almighty "frar"

Technically it doesn't mean anything but is a sure sign of discomfort.
No, seriously go aw-mrrorawmrr-wmrem-mrwwr-frar!
