@OP never call yourself an otaku. it's one of the cringiest things weebs do. Otaku is quite literally just the japanese word for nerd. It has nothing to do with anime. Anime is just one of the many subjects that otakus are known to like. just like in america we have comic book nerds, programming nerds, scifi nerds, videogame nerds, nerd is an all encompassing term for those who are more interested in their hobbies than social interaction or physical activity. Otaku is the same thing. I wanna punch every weeb that calls themself an otaku.
For reference, I watch 10+ shows a season, go to anime conventions, and i've been in multiple anime clubs. I'm not a hater judging you from outside your world, i'm giving you a tip as a brother. Injecting random japanese words into your sentences, using japanese inspired names, they're giant red flags to stay the fuck away. Ditch that part of your personality. Even when you're with your fellow weeb friends, try to do it only sarcastically.
