Schrödinger's asshole. It's testing boundaries. If you say something, they'll claim it was just a joke. If you don't they'll keep going and likely get worse.

This is how assholes test your boundaries to see how far they can push you. It wasn't a joke until you pushed back.

It's called bullying.

They're bullying you.

Depends. Sometimes they take a bad swing at a joke and realize they fucked it up... sometimes though they're just assholes they are trying to cover being an ass.

It's usually a matter of context to tell which is which.

this is known as schrodinger's asshole. they are serious or kidding depending on the results they get

There is this strange belief that humor is exempt from consequences.

In the book "Jam" by "Yahtzee Croshaw" there is a post-apocalyptic sect formed by a group of people from an internet forum. They are not stupid of course; they form a sect ironically. Then they worship a rambling drunk old man called Bob ironically and have ironic sermons and ironically imprison nonbelievers at the ironic orders of the High Priest.

If you point out that this is stupid and evil, they will roll their eyes and go "Duh!", then ironically execute you for heresy.

Ugh, I have a friend whose humour often involves mean-spirited jibes and put-downs. I was in a low mood one day and told him I didn't like the tone of his "jokes", that they sometimes stung. He really dialled back after that.

Most of the time they're just assholes.

In the terms of the cliche, they're trying to have their cake and eat it too.

They want the immediate gratification of being rude assholes, so they do it just long enough for that initial rush, then they back away to try to avoid the consequences.

Maybe they're republican

Because the last thing some people want to do is be accountable

They really think everything is ok as long as it's just a joke

Because punch them in the face. That's how you stop that behavior.

Oh, did I punch you in the face? It was just a joke!

And suddenly they think twice about being an asshole.

I think that some people are just assholes. And other people are too sensitive.

Sometimes its a bit of both. Sometimes its one or the other.

I enjoy mercilessly shit talking people who mercilessly shit talk me back. But I have the social awareness to recognize when this isn't appropriate, and to treat people the way they want to be treated, not how I want to be treated.

Along with assholes testing boundaries that others have said. It can also be someone trying to be witty and speaking before they processed the implications of what they said. I know I have done that but I also showed regret when telling someone I meant it in jest.

Your examples are clearly not that though they were just an ass and didn't want to deal with the consequences of being such.

Depends are we taking annoying stuff?

Then it might be that you didn't understand their sense of humor.

Are we talking rude things ? It's hard to say. Without being there I would hesitate to judge in either direction. Was it that they were actually being rude and are just an asshole? Was it not that bad and you don't get their sense of humor? Is it that you actually have no sense is humor? It's difficult to know without a lot more detail.

The fat ass... That is difficult to judge.. Yeah up front I'd say yeah it's rude and would never do it. But I do know people that do talk to each other that way and neither person has no problem with it. Again I wouldn't but I'm not there so... It's hard to say why that exact group does it.

Did you or did you not move your fat ass?

there are so many ways to approach this but i like to see it as decency being reduced to a mask people wear- their true selves come out every now and then. you can subsequently ask what are the conditions for these outbursts? general malaise, exhaustion, pressure, and all the myriad things our moods are vulnerable to.

Given your example I assume its in person. You can't take anything online very seriously as you don't know if you talking to an 8 or an 80 years old physically or mentally. Ironically I will now continue giving my online opinion as if it matters. From my experience the only time this could be a joke is among a group of male friends who are close. Maybe some females are like this but not in my experience it not as common. Its like the talk you might see in bbc where their always calling each other cunt. Now once in awhile the group might be together and their migh be some new folks or strangers but there is enough folks from the group where one will fall into the mode of acting like that even in mixed company. Some guys like to push to that level of intimacy (they won't want to call it that. intimacy with other males. but thats what it is). Some families related in this way and as I said im sure some groups of girls might and it might even be common now for all I know. Anyway though this is a very particular scenario and any other thats just an insult and the joke thing is something weak individuals do because they say things looking for other people to back them out and when it does not happen they don't have the spine to meet their mouth.

Just ignore them, and if they don't tell them to stop, and if they have a hissyfit over being told to stop don't labour the point.

it's a sign of immaturity, imo. a "look at me, senpai" move that hurts other people.

There's the reason everyone else is giving. And then there's also they just said something rude as a tease and didn't really mean it.
