My Ds has ASD. One of his bullies was very much ‘annoying, weird, selfish, provocative, and worse.’ Everything I later learned suggested he had learnt to be that way to protect himself from similar rejection my Ds faced at primary school, by being the loud, outgoing, up for it, class clown. (Ds tried it briefly as an opposite of himself strategy.) The one who’d do the impulsive rude thing for attention, ‘liven things up a bit,’ often encouraged by the class. It gave him a little status with some kids and was primarily seen as ‘naughty’ by adults. He was also overweight which added to the social stigma hit in secondary. (There was a lad at Ds primary in exactly the same position including weight. In secondary his behaviors changed as he realized they no longer worked and was able to adapt.)
Yr 7 'loud lad' was doing the same things but now mainly only encouraged by the disruptive kids who actively didn’t want to learn.
He saw Ds was ostracized as ‘weird’, first tried to force him to pair up, responded to disinterest stupidly, then sought to make Ds an even bigger target. Trying to regain earlier popularity, he upped his game over appalling things said to female teachers, did more and more stupid things, and targeted Ds heavily.
Ds got into trouble for accusing him of ‘working really hard to have surface popularity so as not to be the one torn apart and now it’s compulsive and you're finished if I go.’
Ds could see what everyone else saw as disruptive, rude, stupid etc was the only shield saving him and tried to use the threat of his withdrawal as the whipping boy to control his actions.
Lad was eventually diagnosed with ASD and OCD.
Because of how ASD presents stereotypically, including tending towards rule adherence, a child who’s absorbed adhering to 'I am the disruptive clown rules' easily gets missed and mislabeled for years.
I am not suggesting this is your son, more trying to show how that profile can evolve hiding what's behind it.
Maybe things are better now, but IME diagnosis (Ds has a few) doesn’t get quality targeted help, what it does is offers a framework to understand and try and work with.
As Gilead has said, social stories can be useful, but a lot depends on the person and if things are correctly adapted to meet their needs and wants. If I’d tried to do social stories ‘direct’ with my Ds, he’d have point blank refused. By the time I knew he had ASD he had no wish to ‘learn how to be accepted,’ he was done.
I slid ideas in under the guise of animation, puppetry and shadow puppetry, theater, working with animals and talking things through.
