Facebook Chat Meme Codes is a Chrome browser extension that turns the normal emoticons display in Facebook chat to a meme emoticons chat. When installed, open a new facebook tab and just press the smilley in the bottom left corner. You will see a table filled with emoticons. The other person you are chatting with, can see these emoticons even if he/she hasn't installed this addon.
