A name of a girl who is smart. She is the "mom" of the friend group (if you're going on a trip she's the one that makes everyone sandwiches and cuts off the crust) . A "Goody-two-shoes" if you will. If she were a spice she'd be vanilla. If you could describe one object that would represent her personality, it would be a soggy newspaper. She is very extra.
Friend: "Why did you pack so many snacks?"
Simmerly: "I just didn't want anyone to get

hungry on our trip!"
Friend: "Trip? We are just going 30 minutes out of town! You're such a Simmerly!"
