Horses and kids. Horses bc they have big heads and a tiny little mouth hole that will suck your whole arm in and bite it off. I also say kids bc some kids ive seen before act like animals. Normal kids are fine but the animal like ones make it very hard for me to resist punching them in the throat.

I also dont like bees/wasps bc i dont like getting stung but i think theres a general dislike for them overall anyways.
