Chucky Grunts

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."
