I want to take my W and points with me. Not giving them back. lol
What does mean, when a player refuse to rematch ?

It means the other player has unreasonable expectations and a sense of entitlement.
Entitlement would be you expecting a rematch. No one owes you anything.

It means they want to play someone else or don't want to play anymore currently. There's plenty of people on here.

if you really must know, I will tell you. when I beat you, and you hit rematch, I am sitting there with my feet up smoking a joint and laughing maniacally at that rematch button flashing at me, but I have no intention to press it. maybe I must walk dog. maybe I will make tea. but first I will observe the button for some number of moments before closing the window, while you wait in agony.
