I used to have my high school English boys class stand in two opposing sides with lists of Shakespearean insults and hurl them.
Yo dog faced cur!
They seemed to like that
That’s not the same thing.
I knew a second grade teacher that stopped kids calling other morons by reading the definition of a moron as someone with the intellect of a nine year old. Since they were seven he said that calling each other a moron was a compliment.
He then made some dunce caps and started a Moron Club for kids that did work exceeding grade level. I the kids above grade level got to wear the hat.
It was pretty funny.
