A word that most people use wrong gets a BOOBOO tag. For instance,
明けましておめでとう!(あけましておめでとう) is usually translated as "Happy New Year!" But if you use this before Jan. 1st, you might as well hold a huge flag up over your head that says NOOB.
Or 話す(はなす, which means ‘’speak’) Only noobs say "あなた は にほんご を 話す?ー ’Do you conversation Japanese?’
You’re supposed to say ”あなた は 日本語を 喋る?”( あなた は にほんご を しゃべる?-’Do you speak Japanese?’)
So 話す also gets a BOOBOO tag.
