What character just makes you mad purely by existing?

And I don't necessarily mean by being evil or whatever, there's plenty of villains we love to hate in the SW universe. I mean the type of character that comes on screen and you just want to watch them get eaten by a krait dragon for no other reason than it makes you happy.

For me it has to be Rose from the PT. One of the only characters in the films that I consider to have no point whatsoever, and her whole intro scene where she's fangirl-ing all over Finn is so cringe it actually makes me a bit nauseous. Obviously the PT has its... problems, but I consider Rose to be one of its cardinal sins.
