What is Surge coin?

Can somebody explain some of the insights and logics behind Surge coin?
Seems everybody got about 145 coins for free; according to the DEX it is now worth 24107 USD.
I assume that is nonsense, so why is this coin appearing and what is the catch?

You can not sell it, thats the catch

ok…so that renders the coin useless? Or what is the point of this?

It is absolutely useless
