D for Deadbeat

Backstory: I’m going through the process to change my name after marriage, and needed some info on my dad, with whom I don’t speak.

Me: Do you remember Dad’s middle name or initial?  I need it for a form and don’t want to email him.
Mom: D
Mom: for Deadbeat
Me: Right.
Mom: J for Jackass
Me: …?
Mom: or Joseph.

Love, Mom
