There was a girl in my HS with the nickname Scrotum and another kid with the nickname Grody Face.
80s and 90s were brutal for in-person bullying, but no way would I want to be a teen with social media. Strangers roasting you!
Honestly I don't really remember hearing much bullying through nicknames in highschool. What I did hear about or witness was almost entirely homophobic stuff, calling people the F-word etc. My school was predominantly white, for the record.
I was faced any real bullying thankfully, in large part due to having very popular friends because in my first HS year (7th grade) I was definitely a stereotypical nerd in all black with a metal band t-shirt on. I most definitely wasn't popular but I became good friends with the popular kids in our area of our school because a lot of them took the same bike route to school so eventually we all cycled together and became friends. So because I was known to hang around in that crowd, bullies tended to leave me alone. Those popular kids were all great folks tbh, and I saw the more jacked dudes step in if they saw someone getting bullied in 'our area of the school'. Overall I'd describe that group more as laid back hippies than the stereotypical douchebag frat bro imagery most would think of when hearing "the popular kids."
Our school was divided in 3 separate areas depending on the type of classes you took.
A levels was the the hardest and intended for students who expect to go to college/university after graduation. The 'classes' (think of 'majors' in the US), were like Greek-Latin, Latin, 8h/week math, 6h/week math, and then Humane Sciences. Graduating in A levels is worthless if you don't go to college/university after.
C levels in terms of education is very very minimal education and focuses on preparing you for a manual labor job immediately upon graduation. It's sole purpose is to make you fully prepared to immediately go to work or start a business as a construction worker, electrician, hairdresser, ...
The level of education is so low that only 3% of people who graduated HS in C levels pass any attempt at college/university, which is heavily discouraged.
B levels was kind of an inbetween. Unlike A levels, you also graduate with a business license like C levels. But the classes here are less hard than A levels and tend to push you more in direction of sales jobs, office management, ... etc. It's basically a middleground. College/university isn't required but it also isn't discouraged.
So our school was kinda segregated in that way, which is kinda wild looking back at it as an adult. Our A levels' building was much bigger, mode modern and far more cozy in terms of couches etc.
Each level of education had their own area. Bullying was a lot more rampant in the C and B levels areas of the school from what I heard.
Admittedly when I was in the 2nd grade, a black boy joined our entirely white school and I'm ashamed to admit I initially bullied him right on his first day by referring to him as "chocolate jar", something I probably picked up from having an extremely racist dad. I had never seen or met a black person irl before at that time but my dad was extremely racist and frequently used the n-word if my mom wasn't around.
Thankfully my mom heard about the new student the same day and was notified that I and a few others kept mocking him as "chocolate jar", so she took away my Gameboy for a month though and gave me a thorough lesson to condemn anything my dad said about black people, to call others out for it and to never partake in any racism ever again.
We all apologized to the boy the next day and became friends, in fact those of us who initially bullied him are still good childhood friends to this day, all these years later.
For clarity, my dad was extremely abusive and supposedly wasn't like this before they got married. I was obviously too young to vouch for that, so I only knew my dad as an extremely racist and homophobic domestic abuser.
Thankfully my mom made sure from early on that I was raised right, and she taught me a lot about the history of racism, why it's so harmful and wrong etc. Basically making sure I'd never turn out like my dad.
