A portmanteau of the words "Old" and "Otaku": i.e. an old person that comes off as disenfranchised with Otaku culture; seemingly uninterested in current trends in anime fandom, but is still passionate about old anime because "they just don't make 'em like they used to!".
Jack: So what do you think of the Summer line-up? Anything you're looking forward to seeing?
Ben: Pfft, I'm not interested in that moé weeaboo crap. Cowboy Bebop was the greatest anime ever made! The Japanese should know that by now. Why do they even bother trying?
Jack: Oh Ben, you're such an Oldtaku.
