The Pony Epidemic of DarkSpyro started in early 2011 and still continues, to many people's anger. It spreads fast, claims all without mercy, and fills brains with cutie marks and sonic rainbooms. Symptoms include the posting of pony topics on the Stuff and Nonsense section, the adopting of a My Little Pony avatar and using phrases suchas 'hey, everypony!'
The reason for the spread is that Lauren Faust includes a signal that takes advantage of some people's hidden pony fetish; and it turns you into an unlovable manchild. (Which may or may not have been the case before)
