A fact freak is someone who likes to spout random facts about nothing in particular at random moments, and/or takes a great interest in trivia but doesn't have any 'real' interests.

Says "did you know..." a lot.
Fact Freak: Did you know that the astronomer that discovered Charon named it after his dead wife?

(Thats the kind of stuff they come out with regularly)
