The word grom is shortened from the word grommet. Used mainly in surf culture, but is also used in the skateboarding community as well. A grom is young kid, usually under the age of 15, that likes to surf or skateboard. A grom refers to both genders male and female. Groms are known for going out either in the oceans surfing or streets skateboarding, but not just surfing or skating, but surfing and skating with all their hearts, with passion like any professional in the extreme sport world. . Groms are usually super chill and positive. They like to encourage their fellow surfer or skater friends. There is no room for negativity in the surfing, skating world. That’s not to say they aren’t competitive because after all that’s only human nature. Who wouldn’t want the chance to be sponsored by some really rad companies and travel the world doing what you love. So groms do have a competitive streak. Groms, kids that dig the extreme sport of surfing and skating. Having fun and living to catch the next big wave or skateboard down the ramp, doing tricks and just being an awesome kid.
That grom is a rad surfer.

A title that used to be cool, is now an insult. Used for someone who surfs and slap boxes for no apparent reason. Gets drunk at least 4-5 times a week during the school year. Thinks they’re funny. Shacks (vapes) in the bathroom. Calls girls dabs ( D DRUNK A ASS B BITCH) yet cant handle their alcohol at all. Is usually high (no shame in that though.) Most likely will never move out of their parent’s homes. Sags their pants. Assaults girls. Basic definition for high school douchebags.

I hate the groms I don’t want to take out with them. They’re just gonna explain to us why we should suck their dicks and then tell us and the rest of the school how badly we suck dick at sucking dick! Lose lose situation😒
