I had a boss that used to refer to me as Dumb Dumb Head.
“Hey Dumb Dumb Head! You forgot to insert the correct date on this wire transfer!”
“Hey Dumb Dumb Head! Don’t forget to take your lunch break!”
“Hey Dumb Dumb Head! Can you show me how to copy and paste again?”
I liked my boss despite the name calling. Maybe it was just Stockholm Syndrome.
