When you're about to talk to someone on Facebook Chat and right when you click their name, they immediately go offline.

Usually this happens due to Facebook's shit chat system or on the rare occasion, the said friend had mind reading powers and read your mind and then purposely logged off on time just to be a dick.
"Hey Geoff, did you finally get the nerves to talk to Sally on Facebook?"

"Yeah, but when I clicked her name she went offline."

"Curse you, Facebook Chat Tease!"
