What's a creepypasta? I know what it is. I listen to people read them on an almost daily basis. Although what's your definition of it if you were to explain it to someone.

Spooky stories roaming the Internet.
Original copypath name.
It is divided into many ways if it could be written.
Maybe - ponypasta, happypasta.
It is not horror horror because people are awakening something different from creepypasta. (The cause of horror makes people feel strange than fear) Creepypasty is to make people scared.
There is much more, but this is the best explanation
