I want to know what "marumaru" means


What does _marumaru_ mean?

For example, this anime title ひとりぼっちの○○生活 (Hitori Bocchi no Marumaru
Seikatsu). What does _marumaru_ mean here?




まる is a name of this circle symbol, and `○○` is read out loud as まるまる, なになに,
etc. It is used to make a placeholder or to mask a part of a sentence/word.
English equivalent is `**`, `__`, "blank", "blah" or "bleep". In this case, I
think the author used it just to make the title look more interesting.
