Okay this is the part I don't get.
I don't see it as type related at all as to whether someone likes to do insults with friends. Maybe there are type related differences in how it's done, I didn't check that closely. But I do recall an LII trying to pick at me, throwing his own version of insults, and he got a response from me that he found too aggressive (and it was not a joke at all from my part, let alone light). So he retreated. Then I asked why he was even doing this and he said this is a way for him to see who he can be friends with, because they won't be responding like that or something. And yeah, no, I found his style too passive-aggressively sarcastic.
The other thing I don't get is why this is such fun if an "attack" is not done for real, for some real target/goal, just as a light joke or whatever. "Joke" here specifically means light, not serious and not intense enough in any way. Mix that with just pretending to do aggression and I'll find that boring and aimless pretty quickly. But then I don't know how EIEs do it I guess. I have known two EIEs for a decade or more, they are pretty close friends of mine, and neither of them tried to insult me like that, ever. After reading up on these things here before, I actually asked each of them as to why not. They said they just didn't think I'd want that. Okay, no idea about these things. End of story. :shrug.
Last time I did regularly insult others intentionally like that (not entirely serious stuff, though it probably looked too aggressive poking, again, was NOT light jokes at all, so it was serious in that sense) was when I was a kid in middle school and I then got hated on stuff so I assumed that was part of the reason. Again, no idea. Been many years ago. Since then, almost no experience with any of this stuff with people except for definitely not entertaining things like the annoying passive-aggressive jabs like that LII example above. The closest example I can recall is when I was once in some unusual mood while talking to an ILI who didn't mind me going pretty intense crazy (NOT light and most definitely not passive-aggressive jabs) and who actually enjoyed it.
Angry, for real, or as a joke? As a joke = doesn't compute for me. I have no problem with real anger, as fucking angry as you want to get, sure no problem. But mixing it with just joking, I don't get what you mean by that. I don't know what kind of mood exactly that is. See the rest of my post above.
Oh and reading your exchanges with Pole Ninja here, where you started with saying the sadistic thingy about LSIs, I'd have just taken that as some generalization meant in a humorous tone, and not at all directed at me so no reaction from my part when I read that beyond finding it a bit funny. (Not too lightly funny, a bit more intense kind actually, but just a little dose of that.)
