I'm going to call someone a rude name to their face for their bad parking.
Why would you want to call them a rude name for that?
I feel good about myself when I'm being mean to others.
It's understandable if you're not happy with someone's parking. That doesn't mean you have to be rude about it. You can tell them that politely.
No, I want them to feel bad about their terrible parking.
Making them feel bad by calling them a rude name isn't going to help them to park better. It would be more helpful if you kindly let them know that they didn't park well.
