The next time someone cut's me off I'm going to curse them out.
Why do you need to express yourself that way.
I think it'll be pretty funny and justified because they deserve it
Wanting to get back at someone for cutting you off is normal but that doesn't mean it's something you should do. Focus on just being safe while you're driving. If you take the time to curse someone out while driving, can you really say you're still being safe or are you now being distracted?
I'm doing this just to get back at them and if they get offended too bad.
Its not just them being offended, it is being safe.   You could end up hurting yourself or others drivers who were not involved.
