Someone, ideally, but not necessarily, of Greek descent who is known among friends as being routinely very philosophical in his or her Facebook posts...even at the risk of making them too lengthy.
Valentina: Angela is always writing these long philosophical posts on Facebook.
Alexander: In her defense, her posts are interesting, and make you think.
Matthew: Yeah, but they're so wordy, I can't always read trough them.
John: Yeah, well, you know, what do you expect, she's just a Greek Facebosopher, after all.
