Have you been given any nicknames by any coworkers?

I was given the nickname “The Beast”. I was overtiming on the overnight shift when I was still a corporal years ago. The captain needed a forced cell move completed and the S.O.R.T. team doesn’t work overnight. They always used the biggest and strongest officers to do them overnight. There’s five officers who go in. The first one has a shield and the other four are etched assigned a limb to subdue. I took a running start, burst into the cell, and rammed the inmate against the wall knocking him unconscious.  I was then called “The Beast” by the supervisor filming the incident. It stuck.
