Narcissism.
Attention seeking
Having zero doubt that they might be wrong. Some people exhibit this in any disagreement and obviously it’s annoying. Taking a look at any comment section on a political post will show you MOST people have this problem in at least one of their beliefs. Self doubt can be destructive but it is required to learn and grow as a person. Try to remember that before blindly shutting down any argument.
Arrogance.
Not the one coming with ignorance in your teen/young adult years.
I mean arrogance from full grown adults.
“I had a really bad day.”
“Well if you think your day was bad, wait till you hear about MY day.”
