Weird isn’t it? Part of my cheek, just below my right eye. was laid open and bleeding a lot. Still had bandages there when I returned. I can’t even locate the spot any more.
My friend’s scarification was his cheek below his eye. A rapier wound look.
“Jazz”, but that’s a pretty obvious one. When I was child growing up, I would occasionally annoy/exasperate my brother (not often, of course, because I was oh SO sweet), so he would say something like, “Sorry, Princess, you actually aren’t going to get your way this time.” It was a sarcastic reference to the Disney “Princess Jasmine”. In other words, my every wish was definitely not his command. LOL
My mother called me Bugs, due to both the cartoon character and I was fascinated by insects.
My father called me George for no apparent reason. Possibly because I couldn’t say Sylvester.
Due to my last name, there were countless variations of wolfe:
Wolfie
Wolf man
Wolf Man Jack
In the mid 2000s, it became Wolfowitz at one unit.
At my last duty station, I was in charge of a small shop full of Pulp Fiction fans, so I became “The Wolf”. That carried over when they merged us into another squadron, to the extent that the commander used it and younger troops called me Master Sergeant The Wolf.
Our yearly hay delivery occurred yesterday, reminding me of a nickname the farmer gave my gf a few years ago.
It was pre-COVID, so my gf worked in Pittsburgh. Hay delivery was scheduled for 6 pm. The hay arrived and my gf wasn’t home yet. The farmer tossed bales from the truck and I stacked them. When we finished, I was huffing and puffing, my shirt soaked through with sweat.
That was when my gf arrived. The farmer greeted her, “hey, Blister, how’s it going?” We both looked at him, puzzled. “Like a blister, she showed up after the work was done”.
When I was a baby, my dad called me Juicy Fruit because I drooled so much. Then when I was older he called me Boonie, which harkens back to the song, Down in the Boondocks. My grandma called me Pet or Cupcake. Pet, because I was her first grandkid and her favorite! and Cupcake because I always asked her to make chocolate cupcakes when I was at her house. In school, some kids called me Ragu which was a play on my last name. Later my niece called me Hodie, when she first started talking. She still does and now she has her little girl call me Auntie Hodie. Other than that, I don’t have any nicknames currently.
My father called me “Nooskie,” for reasons he could never explain (he was high or drunk most of the time anyway), my mother has called me “Dude” since she and I watched Bill & Ted’s Excellent Adventure back in the 80s.
For decades I’ve been “Homie.” It originated in college, a diminutive of my last name (apparently college-age men don’t call each other by their first names). It’s also a synonym for “friend,” and I’m a friendly guy, so now pretty much everyone who knows me calls me “Homie.”
Another one, which I’ve remembered after seeing some mentions of college nicknames:
In my junior and senior years of college (i.e., 1985-87), I was nicknamed “Herb,” by some of the guys in my dorm, after the nebbishy character in a well-known (but disliked) Burger King ad campaign. My girlfriend, who also lived in that same (co-ed) dorm, was named Meg (short for Margaret), and so, everyone called us “Herb and Marge” (making us sound like a couple in our 50s 
).
The “Herb” nickname was used so often that there were some people in that dorm who didn’t realize that my actual name was something else.
Tenth grade Phys-ed class (even the teacher) called me “Mongo,” probably because I was a bit of a hulking kinda guy. They were an OK bunch.
I worked in an office supply warehouse; four guys, two were nephews of the WH manager who called us by our initials. One of the nephews and I had the same first initial, so he was J-1 and I was J-2. Then J-1 started slacking off to the point of dismissal, so I became J-1. When nephew J quit, I became J. They nicknamed my car The Gray Ghost, because it was 95% gray primer. Hey, I wasn’t going to waste paint on a Chevy Citation.
And you were only pawn in game of …whatever y’all played during Phys-ed?
I may have punched out a horse – high school was a blur. 
Speaking of horses…my gf has a mare named Gracey. She can be a bit derpy, so we call her GrapeSeed.
(ETA: the mare, not my gf)
Was that cause-and-effect, somehow?
Some friends call me Reverend Tim because although I’m an atheist I was ordained by Universal Life Church. I use Revtim as a username whenever I can, including here.
Hmm, several.
Missy China Blue Eyes by my dad and a couple close family friends when I was little. Reason is obvious.
Johnny - by my step-grandpa, this for being such a tomboy
Sha-Sha-Boop - horrible, embarrassing family nickname. It came about because my older brother couldn’t pronounce my name when I first arrived home from the hospital, it migrated into something else (much better) which the family still use today.
The Bionic Arm - this after stagehanding the high school musical. It had garage doors we used to roll set changes in and out. They greased the rails and didn’t tell me. First set change time and I opened the garage door by pulling the counterweighted rope as usual, but the door flew up and got stuck. This happened twice, before I was able to moderate my big yank into something less powerful.
Art - this one came from answering the Art Dept phone “Art Department” and then a friend who was calling asked “Is this Art?” I only have one friend who still uses that nickname.
Another one that I’m not willing to divulge lest I get recognized here by someone I know. TubaDiva got it right off the bat though and she didn’t even know me firsthand - yet. 
My surname is also a nickname, as it is for my brothers. It just fits us.
You also fell off a toilet and broke your arm.
Never really had one. My father-in-law generally calls me “Man”, because when my wife and I speak for or to the dog she’s “Lady” and I’m “Man”. “Be patient, puppy. Man will take you for a walk.” And it seems we did a lot of conversing with the dog around him …
She has worked from home since the start of COVID.
My cousin’s second child is Charles. They planned to call him “Chuck”. Her first child could not pronounce that correctly - so Tuck he became, and Tuck he remains - he’s in his 40s.
My nickname in high school was a shortening of my last name. Almost everyone including the more relaxed teachers used my nickname.
When I went to University (college) it took quite some getting used to being called by my actual name. People would use my name and I wouldn’t even respond.
