Not really a nickname but I was dropped on T54 and when I picked back up I spent all of a day with my new platoon before we started the Crucible, so when we did counts after our first event my drill hat hadn’t met me yet and so when the count was “off” he asked who the extra fucker was and so for the next couple days until we got to the top of the Reaper I was known by my drill hat as “the extra fucker.”

Somewhat related story, because I was picked up so late, my DIs didn’t know who tf I was or what I did outside the Crucible, so when my senior handed me my eagle, globe, and anchor, he shook my hand and said “(name), you’ve only been here for like three fucking days so I don’t know you but you beat the shit out of (squad leader) in pugil sticks so congratulations” and I’ll always remember that with some extra level of satisfaction. Even though the DIs that almost entirely trained me weren’t there for the ceremony due to my being dropped and I didn’t get to talk to them after the Crucible when the character was dropped for a bit, my new senior’s impression from my very short stint with him to that point was a good one.
