I changed schools like 4 times now. I've seen a lot of gegbulls. I'll mention one particular instance that was fucking terrifying
Autistic kid in 9th grade. Calling him a gegbull is hard since he barely did anything, and he barely attended any classes, there would be months where he didn't attend a single day, but whenever he did, something chaotic would always happen. It's worth mentioning as well that his autism was extreme, low-functioning, he could speak, but he could barely do anything else.
I got in a fight with him one day - he was a notorious pervert, there was this scandal with him and another girl where he kept taking pictures of her getting out of the bathroom. I used to have a black friend; said autist would commonly shout racial slurs at him, calling him a monkey etc. I had enough of this and mentioned his incident to him.
He then asked me; "did you tell any of this to the principal?". I said I did, of course I did, he's a fucking pervert. That's when the fight started.
It was very convoluted and I'd rather not spend 5 minutes talking about it here. But, in the end, he got suspended for 2 months, and I ended up with open sores on my mouth (he tried ripping it open) for 2 weeks.
I then left the school. I don't know where he is now.
