Grimmer Middle School 

The best place to find sluts, assholes, fuckboys, druggies, and alcohol. If you don't start drinking or vaping by 5th grade you're not cool at Grimmer. It's a school in Schererville Indiana and let me tell you . . . . It's a fucking vape store. Grimmer middle school sucks ass.

I hate that bitch, bet she's from Grimmer Middle School.
