Butcher their native language, then invent words to explain things that can no longer be explained. Case in point: unalived. Only those without access to a dictionary or thesaurus would need to use such a cringe-worthy term.
When someone is dissapointed after they get a opinion. Example: Someone says "Hey, check out this cool art I did! Rate it from one to ten!" then another person says "4/10, doesnt look that good in my opinion." and then they rage about it.
Not admit to their mistake or outright refuse to.
I know several people that will make excuses all day or twist what happened to their liking all to avoid admiting their wrong or taking responsibility for their behavior. It's even more maddening when that person is your supervisor or manager. Me: "But you were the one that told me to do (thing that got me in trouble)". Them: "Oh no I didn't. You must have misheard me".
That, and also the people that only find it acceptable for them to make mistakes but have no mercy when others make them. It's like that believe they are the only one's allowed to be 'human'.
