The act of voluntarily or involuntarily grunting under one’s breath when dissatisfied or frustrated with a conversation or situation at hand. A type of non-verbal communication that occurs when someone (usually named Chuck) generates strange audible noises that often puzzle and/or further annoy anyone within earshot.
Person 1: "What's up with your friend, Dude? Why's he keep making those funny noises?"
Person 2: "Oh those are just Chucky Grunts...indirect ways of telling us he thinks we're both assholes who should shut up, quit talking or stop whatever it is we happen to be doing."

Grunt bag : one who is trying too hard to impress his or her peers. A low totem pole individual who wants to be the best when they can't.
