Have you got a Overlord badge

You reach the status in the game, which requires constant gameplay. In OverlorDS, it takes 16,000 something Awesome Points. Read Limxzero's blog for the exact amount.

4/5 People suffer from diarrhea. Does that mean the other enjoys it?

As said you reach the Overlord adminship status within the game which requires(I believe) 16,874 Awesome points(AP).

Don't argue with idiots because they will drag you down to their level and then beat you with experience.

Badge = Overlord rank on any character = at least 16,383 AP

Catch my drift.
