Um, um.... *Trying to think of something* Oh, well, I got a funny-ish true story.
So while I was going to summer camp, I made friends with a group of guys, but also a few other girls. I met this one girl, who said that she thinks that shes this meme, cuz she made that expression a lot, and at that time, she was wearing headbands in stuff, and I can tell you, she deadass looked liked that girl, even when I met her a few years later. I even made her do the pose, and she did it EXACTLY like her, no differences. And she was surprised when I said she was still a valid template! I dont know if she was lying, or making it up, but she really looked like that girl. I swear in my life.
TL:DR
I happened to possibly meet this meme girl in real life at summer camp, and I swear on my life it was probably her, and if it wasn't, she came pretty damn close.
