It’s not as bad as being bitten in the Target.
When I was a kid - this was when SAHM was the norm - I was with a bunch of kids playing ball when the pitcher got hit by a batted ball.
The kid was bawling, and two moms came running out. The first mom explained to the other that “Johnny got hit in the coin.”
That is the ONLY time I’ve ever heard it referred to that way.
