I don't think most folks outside the military flying community (and the fighter/bomber community, more specifically) appreciate how callsigns actually *become* your name when it is how you are referred to for years and decades on end.
Two of my squadrons used to have "First Name Friday", on which we were only supposed to refer to each other by our first names. Failing to refer to someone by their first name (or using pronoun cop-outs like "you" or "dude") was a violation that you had to pay in cash at the ops desk immediately. Violations in my first squadron were a dollar, but the second squadron charged $5 for each infraction.
For those who aren't familiar with USAF custom, Friday is also the day in which we wear "Friday nametags" on our flight suits that have our callsign on them instead of our given name, so that significantly increased the challenge of having to refer to squadronmates' actual given names.
We paid for a lot of squadron cookouts and stocked the snacko fridge healthily using fines from First Name Friday.
