D-sciple
A D-sciple is someone who would fight you for the right to sing along to 'The Devil's Best Friend' in a loud bar at 2 a. m.
I sang 'The Devil's Best Friend' in a bar. Some guy challenged me to a duel. I won by singing louder.
My sister is a D-sciple. She once yelled 'Balls to the Wall' at my dog. The dog ran away.
I told my boss I was a D-sciple. He gave me a warning. I told him he was a D-sciple too.
