What is this site?

Srsly, I was looking up 2chan, which I got to from a blog about japan through a series of browsing of wikipedia (You know, japan to technology to anime to whatever...) and this site makes no sense? What is so good about it?

First of all, I'm a girl. I'm pretty sure that that's only guys. Second, this is what I mean! Why would you purposely come to somewhere to be insulted! I suppose it is pretty amusing though. I'm only 15 and i'm more mature than you, who are probably some fat old guy sitting in his moms basement.
