A term used as cited above (i.e., obsessed fanthing of the Naruto anime), but also lampooningly employed to refer to a fan of Naru Narusegawa from Ken Akamatsu's manga "Love Hina".
"Lisa is a total Narutard. She's got Naru crap all over her cubicle."
> "Don't you mean 'Naruto crap'?"
"Naru, Naruto--who keeps up with what these silly terms mean, anyway?"
