Nman received a "Fail" badge on Nov 16 because their post was full of fail. Like, I mean, the post itself was good. Great even. But the content was, like, kind of "faily." You know? Yeah, I don't really know either.
Nman received an "LOL" badge on Sep 15 because their post made people laugh. Out loud. Not literally. Why do we say LOL when we don't mean it? That's one for the philosophers, I guess. Anyway, point being, their post was funny. That should have been a way easier point to make than it was.
