N1C10R
A relative so far back they might have been born in the Dark Ages, and they still think they're your best friend.
My N1C10R was born in the Dark Ages. I was born in the modern age. I didn’t know what to do.
My N1C10R claims to be my best friend. I told them they were my ancestor.
My N1C10R showed up at my bar mitzvah. I told them to go back to the Dark Ages.
