I’ve already spoken about Koreaboos before. The people who want to be Korean, marry a Korean, want to be just like a Kpop idol or Kdrama star. They reject their own culture in the name of adopting Korean culture (or rather, what they think Korean culture is like).
The weeaboo is almost like this. Actually, they are the forefather to this. The weeaboo, rather than being centered around Korean pop culture, is centered around Japan. The weeaboo rejects their own culture in order to adopt what they believe is Japanese culture, proclaiming it as superior to everything else. They base their idea of Japanese culture off of anime and manga, imagining it as some perfect society that is more advanced than any other culture, and that it has had no bad history or political issues.
The weeaboo began to form around the 1990’s, when the West had access to popular anime and manga. Young generations now had access to watching anime, influencing an entire generation, causing some to go a little overboard and become weeaboos.
Except, at the time, they weren’t called weeaboos. Until the mid-2000’s, weeaboos were called “wapanese”, meaning white Japanese (despite people of all races having the potential to be a weeaboo). The old name was mostly given on online forums, with sites such as Reddit and 4chan coining the terms.
However, in the mid-2000’s, some 4chan moderators decided that they were sick of the term. They banned the term wapanese, causing users to scour the internet for another name. This is how they found the term weeaboo. The term came originally from an obscure comic, which is in no way connected to the actual group of people. However, it was a word that also didn’t have a meaning of its own, and was thus made what it is today.
Weeaboos are still going strong, although they now have to compete with koreaboos, causing an ironic and hypocritical battle between the two groups. They are both disgusted with one another, but can’t seem to relate the traits of the other groups back to themselves. It’s kind of weird, but amusing to watch.
