a non-japanese person obsessed with japanese comics/cartoons called anime/manga
here are examples:
1.they commomly only care about anime/manga like for example if a different country invented anime/manga they would be worshiping that country.
2.they use the following japanese words:
(also commonly said wrong and mocking)
-desu (doesnt really have a exactranslation but used as is or mine at end of a sentence)
-kawaii (means cute)
3.in extreme cases a slight insult of anime/manga causes them to overeact and resorts to violence and cussing
unfortunatly this has developed a group of haters called antiweeaboos that sometimes overeact
like if someone reads manga and anime alot yet it isnt there world they would be classified as one
personally being japanese-american I really find weeaboos annoying and i feel offended around them sometimes
yet not all weaboos are horrible people some are just kind,missunderstood,and yes a overboard crazyfans
(this excludes 40 year olds with no life and people that hate everyone that hates anime aka mean weeaboos)
so i feel neutral on the subject.
