Neurotypical here, i just find it funny without context. Its just a joke if its not malicious. The thing is, theres a line between funny nicknames and namecalling but sadly school kids often overstep it. Thats why school should teach them that its not okay. For example with my past waterpolo team it was a kind of “friendship language”. My nickname was bird or angrybird but we had all kinds of things like: microwave, hamburger, etc(all in hungarian tho because im from hungary) .
