You know what kind of people make themselves look like culturally ignorant morons? Rich white kids trying to act 'gangsta ghetto' trying to convince me they're something they're obviously not.

I'm sorry, but you're not an anime character. It is not appropriate to run up to strangers and act out your impression of what you think a cute/funny/badass japanese person is based on cartoon shows you are fond of in hopes they will think you are these things. This isn't a cultural thing; this is something only anime fangirls/boys do. I've never gotten this from a non-anime fan. Ever. No one is confusing you for a serious person trying to seriously learn Japanese. This is on par with Dumb white kids regurgitating black american rap cliches thinking it will make others think they are part of this culture that they don't really know or understand.
