Mintpicker

It's a newer term without a definition in the Genshin Impact space referring to someone who doesn't have anything to do in the game (because the game doesn't have enough content outside of questing and event minigames), so they will endlessly farm flowers and other resources around the world as a way to derive enjoyment and keep playing the game.

The term itself is used in much the same way as telling someone to "go touch grass" or "go play a different game."

Anybody above adventure rank 56 is such a mintpicker.
