I say XD a lot and it's kindof like a saying for me just like ^.^ was for me too. I was wondering what you say a lot?
My answer is obvious: "Kinky." EDIT: Unless we were talking about emoticons, then I just use and such.
I don't find smilies something you "say," so... uh I say shizz a lot, and asdf, asdfghjkl;' and wat. And lulz.
I typically don't talk to people. I just work on my little project on my continent and keep to myself. I guess I'm a hermit
