People Who Think They're Absolute Geniuses

You could call it narcissism, a compulsion to brag, or just a lack of self awareness, but some absurd people think they're total geniuses and they absolutely must let everyone know online. Methods include saying you know how the universe works, bragging about being an "early reader" and completely missing the point of a joke. There are a good amount of ridiculous people out there who think they're geniuses.
