Honey , why do you keep looking out the front door? OK I admit it, I have a badcase of Amazitis and I can't help myself!
It's when there's something with so much vast quantities of amazing you have no other word to use! It's like when your eating a piece of beef jerky, or the feeling you get when you take a big poop, or when you have the satisfaction of punting a gnome, or the way you express yourself when you give yourself head.

It's Brilliant! It's Far out! It can make you pee blood! It's Amazinism!
