-People in California who don’t know how to drive in any sort of weather
-People who deface historic, artistic, or otherwise cool things
-People who leave their cars on when they aren’t in them
-Papercuts
-People who think the Earth is flat (LOL)
When they talk too much but don't bring anything to the conversation. Or anything in general with any intellectual value. It shows the lack of the smart genes in a person and that is a biological turn off for me.
