What sticker on the back of someone’s car immediately makes you think, this person is an idiot?

1. I'm not sure if this is a really common thing, but anything that depicts Calvin from Calvin & Hobbes peeing on something. I've seen one or two stickers like that before, and... Ugh

2. Most variations or "back off" or "don't tailgate", without fail every single person I have seen with one of those stickers has been inches away from the car in front of them.

3. Salt Life........... We live near ZERO bodies of salt water. And half the people don’t even look like they can swim. I don’t get it, maybe I missed something. Please, correct me if I’m oblivious to something key here.

4. When someone has an excessive amount of political stickers and magnets. Or anything that's commonly known to be offensive.

5. Not a sticker but those testicles on truck hitches. Clearly theirs is small

6. May be a regional thing but I don't like the "in loving memory" stickers. I can't imagine being memorialized in that manner.

7. BOUNTY Wolf: $100 Environmentalist: $1000

8. The stick figures that announce to every possible predator how many children you have.

9. "My kid's an honor student" -- okay, but you don't know how to merge.

10. "Warning: in case of rapture this car will be empty!" So sure of yourself, aren't you?

11. I've seen a lot of those family stickers with the Joker and Harley Quinn as the mom and dad. It's like... you did realize that that's an abusive relationship right?
