Who's the worst of the Mane 6?

Had a sh** morning full of missed opportunities and rejection. Got through it after a few good cries.

I can only wonder how Twilight is able to bottle her tears because she's surrounded by the "less knowledgeable". And yes, I made a jab at the other ponies; like they haven't done stuff in the show to piss us off (like Canterlot Wedding).

Anyway, I've seen a lot of groups ask who is best pony. Well, I'm different.

So who is WORST pony?

My list is very long, mind you, and some of you already know. Please comment which pony and explain why you want that character to fall into a hole and die.
