1. People who talk like they are reading a thesaurus
    You didn't "curate the hors d'oeuvres at your dinner party". That doesn't make sense.
  2. When people make Instagram accounts for their pets
    Unless your dog is posting the photos itself, you have too much time on your hands.
  3. Fruity gum
  4. Overly vulgar/sexual rap lyrics
    When I'm riding in the car with my grandma sometimes it just feels weird
  5. Uncooked peppers
  6. People who don't acknowledge they went through an awkward phase
    It happened. It simply happens to the best of us.
  7. People who refer to their dogs as their children
    I get it, I love dogs as much as the next person but they aren't your kids. They just aren't. You sound crazy.
  8. Blue, yellow, and green nail polish
    Alien hands
  9. Women who put on their makeup on the subway, especially when they sit right beside me (they can sense my impending distaste and find it appealing, perhaps) and use various prongs and clamps on their eyelashes.
