I was called "Little Josh" growing up because I lived across the road from another Josh whom was a few years older than me. So the neighborhood parents used to call us Little Josh and Big Josh.
In elementary school I used to be called "Smiley" because I always smiled and laughed a lot.
When I was in 10th grade I grew a huge blonde afro that descended around my face and shoulders in tight little ringlets. I got many names for that. My dad called me "Sheepdog". My nephew thought it was cool and said I looked like a Roman warrior and called me "Joshimus Maximus". Some girl at school thought it looked like Napoleon Dynamite and called me such. One of the black dudes at school used to call me White Thunder or something like that, I guess because I was white and had an afro.
I got called "The Green Hornet" in the latter years of high school due to many ridiculous, heroic, and downright stupid exploits I performed with my car, a beat-up, piece of shit, green Ford Escort.
I used to be a dishwasher at a Hooters, and my manager used to call me "Turtle" for apparently being too slow. I also once cut myself shucking clams and he thought it was hilarious. Asshole.
My friends and I collectively gained the dubious title "Dem boys" (exclusively pronounced with a thick redneck accent) after gaining notoriety in our neighborhood for staying up all night drinking and pulling shenanigans like running over peoples' mailboxes, shitting in the road, catching things on fire, setting off elaborate fireworks in strangers' front yards at 3 AM, and just in general being nuisances. I think the worst thing we ever did was take his truck and plow through a yard full of expensive Christmas decorations. Anyways, the nickname was first revealed one morning when my friends and I were sitting on the tailgate of his truck after a night of baseness, and his neighbor emerged from his house at around 6 A.M with his wife to go to work. As they stepped out, I was in the process of cracking open another beer, and the "CRRRR-TSHHHHK" sound crackled through the air. From across the road through the still morning air we distinctly heard the man say "Der go dem boys again..." and then they got into the car and left. I think we broke into their house once and stole a single banana off the counter out of a group of 5, just to fuck with their heads. Jesus I used to be bad.
