Act like anime characters

I knew a total asshole back in high school and even after graduating he would still act like an anime character in public. But later I learned that he just has a bad time coping, but seeing how he mistreated me and others I know and being a total hypocrite, he can go eat shit.

Hell, there's someone in my class who really does act like an obnoxious anime character from time to time.

So yeah, there are adults who do still act like anime characters.
