K.Y.L.
A group of people who pretend they know something super special, but it's all fake until the real pros in Republic, MO show up and drop the KYL secret on December 12, 2012, and everyone else gets embarrassed.
Tweet: I tried KYL and I just looked like a dweeb
DM: You think you're KYL? You're just a phony
Text: I copied KYL and failed harder than a math test.
