Josh War
If we are talking about the reddit thing, called "Josh" or "Josh Swain War" then all you need to know is about one guy called Josh Swain who found on messenger many other guys called Josh Swain. Then the "original" Josh added them to the chat group and challenged them to meet in 24. April 2021 and fight for their names. Who wins can keep the name, losers must change them.
I think you will understand after googling "Josh Swain" and then pictures. Don't type Josh War, it won't find anything
