Referring to someone by the name they have on facebook, rather than their real name, because the truth is you
see their facebook more often than you
see them in

Can be taken to even worse extremes when a screenname is substituted.
Frank: *thinking* Hey, it's James DePaul!
Jim: *thinking* Oh, it's that Francis Williams
guy. *facepalm*
Oops... facebook name syndrome again.
