More people do it than you might think! I sit in an office of 8, there’s always someone either quietly beatboxing to themselves, doing minute long "uhhhrrmm"s or muttering movie quotes. There’s an understanding that anyone who feels bothered by the stimming can put on their noise cancelling headphones lol
