"You mean, 'Mark and I ate cookies!'"
"Stop it!"
"Sorry, I have Grammatical Pedantry Syndrome."

Grommet 

Surfer slang (although also extends to other boardsports, and surf sports) for a young surfer. Can also be used to refer to children in general, although usually they have some association with surfing/etc.

Although usually there is no ill-meaning behind the term, it is often used to poke fun at younger surfers. It can sometimes be used as a derogatory term when younger surfers are annoying, bad or otherwise difficult.

It is frequently abbreviated to grom.

On a beach crowded with children: "Where did all the grommets come from?"
