I was talking to a friend today when he told me about an extension for most web browsers (I know Internet Explorer is excluded) where you can use "troll" emoticons, such as nyan cat, the "y u no" guy, "me gusta", and obviously the troll face. Does anyone else use these? If you don't, but are interested, here's a link for the google chrome download.
