This term refers to the group of people that think it’s cool to vape in high school bathrooms. Always skip classes and when they do show up they are high. Are you type of person to scream, “where’s my juul?” after miss placing it.
“Why is there a group of people vaping outside the school?”
“Those are groms, don’t pay attention to them.”

1. The word grom short for grommet is a surf culture slang term that originated in California and is used most often to describe any young kid who's a surfer despite their level of skill.

2. Evolving from surf culture, the term grom is occasionally used to describe young skate boarders, skiers and snowboarders too, though used less often.
"I prefer morning surf sessions before all the little groms get out of school and crowd the line-up."

-OR-
"If that grom drops in on me one more time, I'll teach that punk a lesson in respect that he'll never forget!"

1. n. Describes someone that is young and is a skilled skateboarder/surfer.

2. Downhillers (skaters that mostly skate downhill) are considered groms.
Whenever I visit Laguna Beach, I always see a bunch of groms about to kill themselves every day.

Most groms are sponsored by ABEC 11.
