Since he was carrying a .25-caliber Beratta (probably a Minx) I vote that his new nickname should be:
Donne "Two Bits" Trotter.
The two-bit twit.
“Two Bits” ...
I used that term at work, and the new hires (25 year-old engineers) didn’t know what it meant.
So I had to explain Pieces-of-Eight and chopping them up, etc.
I’m not sure they wanted to know.
Maybe going metric would help i.e., 6.35 mm
