Yes, but chances are kids won't figure out the meaning until late middle-high school. At that point the young adult should be less sensitive to childish bullying (although the way some kids are these days, she might have trouble)
She basically has until Karal the bug nerd figures it out, but chances are he's got his own troubles to deal with.
Do people expect 13-16 year-olds to be more resilient to bullying than younger kids? Are they?
I’d expect that to be the most vulnerable age, but I don’t know. 17-18, I can see, but only because they’re more likely to have more varied social circles, and may be able to find more accepting groups on their own (though that could be a dnd group or an alt-right group, so that’s not necessarily a good thing). Again, I don’t really know anything about childhood development though.
