When something which was supposed to be amazing ends up being not amazing at all. In fact it was quite bad, and by quite I mean that I have never been so underwhelmed in my life, it was almost depressing.

From the words:

Mal- meaning bad AND
-mazing which is shortened form of amazing.
"Far Cry primal is such an malmazing game!"
"I know! I haven't been so malmazed since I saw the superman reboot."
