Mine is rather benign as well. I teach at Columbine and got started reefing when I put a tank in the library after the shooting. Columbine Rebels, thus Rebel.
I graduated from Columbine in 95, my brother in 98, my sister in 2000, and my baby brother in 2005
After high school I picked up the nick name of Angel, mainly cause I was well known as being the ultimate corrupter, and online I have gone by various Syn names ever since then
Good grief is one of my most used epithets and most often in reference to a tank disaster of some type or my dog has eaten something inedible or the kids are running me ragged. So many uses.
