Gafket
A made-up word that means the same as a real insult, but it sounds fancy. People use it so they don’t get caught saying something bad.
"I called him a gafket in the hallway. He yelled at me for 10 minutes."
"She said I was a gafket during lunch. I threw my sandwich at her."
"He wrote "You’re a gafket" on my desk. I wrote it back on his."
