derpyfag 

Possibly the most retarded and autistic people not only in the MLP fandom, but on the internet. Period. They're not only obsessing over something that's ANTI funny, they're obsessing over a fucking animation error. This is a big reason why most people hate bronies, since no group of people have decreased their IQ even as much as below 3,861 as Derpyfags.
