Anyone who is called Cat, such as Katherine, Katie, Catherine, Catt etc, and is an annoying, patronising and rude buttplug.
Person 1: "I don't know how to do this."
Katherine/Kat etc: "God, how do you get through life- seriously!"
Person 1: "hey now, stop being so Catronising/don't Catronise me
Also works in the above scenario if Person 1 and Person 2 are not Kat/Catt, but they both know her, and both know she's an uppity, patronising cow.
