Someone that tries super hard to be cool but really is just a fake wanna-be that totally annoys you.
Man that Whitney dude is such a grom, he pissed all over himself after drinking a few Twisted Tea's. I bet he drops grommer's all the time in bars.

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😒

A young lad/lass, typically 8-14 in age, a peak grom is just 12 years old. Gangly, awkward, and just at the age where they could maybe survive out on their own, but probably not. They get into mad immature and suspicious activity, but aren’t old enough to get into serious trouble. Not all kids are groms though—if you’re responsible, you likely don’t qualify as a grom.
Caleb: Why are there so many groms running around at this concert?
Jayson: Idk bruh, but if I were a young grom I’d probably be here too

Esther: There were these kids at the park that wouldn’t stop throwing pennies at my car!
Mike: That’s some grom activity for real hahaha
