Grommit

Usually, a smelly 5-year-old kid playing roblox. In other cases, they are just really bad gross ugly Faggots. That usually gets pussy from The Boston Street Sweeper and prefer to eat the shit that comes out. That's how disgusting they are.

Boy 1: Wanna hang out with Ethan?
Boy 2: Nah he's such a fucking grommit.
Boy 1: Okay I understand.
