Are there weebs in Japan?

Question:

Maybe "weeb" isn't the right word.

Me and my friends like anime, but we hate weeaboos. In case you didn't already know, a weeaboo is someone who isn't from Japan who loves anime and choose to immerse themselves in Japanese pop culture. Often throwing around butchered, mispronounced Japanese words such as "desu", "kawaii", or "sugoi". They dress like anime characters and act like total dunces glomping people at conventions and being a big waste of space. They believe that by doing this, they will one day go to Japan or something, and that all the people there will just accept them as one of their own, because everybody there will be so amazed by their knowledge of "animu".

My question is, is there anything like that in Japan? Are there people in Japan that are extremely immersed in American pop culture to the point that it becomes annoying? I don't see why there would be, but I was just wondering about it and would appreciate it if someone answered.

Answer:

Not so many now.
