In commenting on viral videos, a person who ignores the message of an entire video to slam the creator for one little, insignificant point.
"After watching my entire video thesis on the economy, al this factard could say was 'd00d, yur tie is crooked'"
a person who shows that they "know it all" when in the audience might assume otherwise, they are considered know-it-alls, but now there is a new word for it! Factard, not two Ts just one. ; )
Billy_Knowitall: Actually, you are wron...
Joe_Dumberer ...Gah Billy you're such a factard!
"You think you know everything but you don't, you're such a factard!"
