I have one of those complicated German last names that got distilled down to "Blaster" on the first ship I served on. Strangely, I lived up to my handle on one of the last ships I served on.
[SEA STORY ALERT] Our ship was on the way to Guantanamo Bay for refresher training when we discovered that for the man overboard drill, the boat officer would have to carry the M-14 due to the required small boat crew size limitation. So, on the flight deck of a flat bottomed LST with consistent 10-15 degree rolls, I was the only officer onboard that was able to qualify on the M-14. It was probably the only time in my naval career that I was considered a salty bad-ass by the entire crew. Even our chief gunner's mate told me, "I don't know how you did that!".
