When you fuck someone so hard that they start grunting in an extremely deep voice, often sounding like a shitty Golem from Lord of The Rings. This low grunting will continue until your partner lets out a massive screech. Signifying their change into the Gremlin King/Queen, they are now the ruler of all Gremlins, truly a noble honor.

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."
