Chattee
Any person or persons participating in a Facebook Conference Chat. It should be noted that a "Chattee" is different from a chat-room "Chatter" because a Chatter spends wasted hours in a chat-room while Chattees spend wasted hours on a Facebook Photo page.
The chattee was Conference Chatting with others from all parts of the world for at least 45 minutes while the one who posted the photo in the first place was no where to be found.
Phantom chattee
A term to describe a person that chats on social media when their status says they are offline.
