Any video game controller that isn't a part of that system's brand controllers. If someone owns 4 controllers for a video game system, statistics show that at least one of these controllers is a Mad Catz, because they're much cheaper than the actual brand controllers. All Mad Catz for every generation of controller includes a turbo button, which royally fucks you over if you ever touch it.

NOTE: Despite the company that the "makeshift" controller comes from, it is still referred to as a Mad Catz controller.
John: "Yo, you wanna play some 4 player Hello Kitty Island Adventure with us?"

Xavier: "Ya, as long as I don't have to use the Mad Catz though."

Get the Mad Catz mug.
Crazy kittens. A clutch of insane felines.
Avast! Those mad catz are sure putting the beatdown on those milkmen.
