I think I figured out what "Dandadan" is
I saw a post a while ago discussing something similar, but some of the points were wrong. It's very easily visible that this panel has connections to Hinduism and so the word "Dandadan" can be broken into two words "Danda" and "Dan" or "Dana" which mean "punishment" and "boon" meaning if Dandadan is an item, It is something that can force punishments or "shraaps" which are curses or blessings which are "boons. Another thing it could be is something similar to what CSG is already using meaning it can take away curses from people like he tried to do with Okarun and give them as Blessings to others which he did with the pygmies girl. The second theory seems more solid as we have seen him use something similar to that in the Manga.
