A non Japanese person who basically denounces their own culture and calls themselves Japanese. They try to learn Japanese through the anime they watch and usually end up pronouncing it wrong and looking like a complete idiot; anybody who claims that they don't like the English dubbing of an anime when they can only speak English.

KEEP IN MIND: that a non-japanese person can like the culture, watch anime, speak the language and RESPECT THE CULTURE, while still keeping in touch with there own. Which keeps them from being a Weeaboo, japanophile, ect.

Weeaboo's basically disrespect the culture and make complete asses of themselves
