"Show off" (Patreon)

You all know perfectly well that I am not a native English speaker. In general, I speak only Russian. One of my patrons constantly writes about a certain "Show off" which, according to him, I lack.

In Russia, this word means the same as "Bragging". That is, to show everyone your superiority thanks to money or connections. I'm sure that's not what he means.

But then I'm absolutely confused, because I have no idea what he's talking about. Can someone explain to me?
