Least favorite character?

Who is your IRRATIONALLY least favorite character in the show?

You can't say Rupert or Nateb ecause both of those are too rational and obvious.

I'm going to get attacked by this but I'm going to say Sam. I can't even exactly say what it is about him that bothers me, except maybe his unrelenting happiness and optimism, which I find fake, but something about his character just bores me to tears. I told you, it's probably irrational! Like, he's fine, but pretty uninteresting and overrated.

Your turn.

Edit: Zava, Jane, Shandy, and Jade are supposed to be disliked, so they don't quite qualify for what I'm asking.
