I was a teenager throughout the 90's and was a bit of a bully from time to time, and I don't think bullying has changed much since then. If it wasn't a pen, it was the shoes, t-shirt, or the way someone pronounced a word.
Bullies are bullies, they will pick up on any thing they can and exploit it to belittle another person.
