dad-a-base - A secret room in your house where your dad hides his old jok

A secret room in your house where your dad hides his old jokes and his secrets from your mom.

Dad: 'I didn't cheat on your mom. I just went to the dad-a-base.'

Mom: 'Why is there a lock on the basement door?' Dad: 'That's the dad-a-base. Don't touch it.'

Me: 'What's in the dad-a-base?' Dad: 'Your childhood.'
