It's a game:)
The question is 'why does everyone hate me'
and each poster posts that question at the end of their post. The next person tries to think of a (silly) reason as to why everyone would hate the above person.
For instance, if you had posted: "Why does everyone hate me?"
I could go:
Well, it's because MrKnott spelled backwards is ttonKrM..
And everyone knows that ttonKrM is Mapalopeian for "born on a Monday with smelly feet".
(Which, ofcourse, is not true but that's the point of the game, to keep it silly and not to point out actual reasons or anything)
After I've answered your question, it's my turn to ask:
Why does everyone hate me?
