Callsign "Sensei"

Albeit a cool sounding callsign the story behind it makes it qualify. I made it through college on a scholarship for the martial arts team. I taught martial arts in various styles both in the service and in the civilian world as well. I had been given a couple of variations of "Miyagi" to "KK" (short for "karate kid") and even WOWO ("wax on, wax off") but finally ended up with "Sensei". There I was... fellow meatbags in a bar drinking too much and hitting on too ugly women. Except for me. I had been voted the designated driver. Mainly because I had a car. It's 0300 and two of the guys decide it's a good idea to have a boxing match and they want me to referee. I was tired and wanted to go home so I thought "How long can these two asshats last drunk as they are?" They start and they are fighting as well as drunk, untrained fighters can fight. One throws a haymaker no where near his opponent and clocks me right in the eye. Me, the sober, martial arts "expert" is the only one who gets hit. Next day at the squadron I get grounded by the flight surgeon because I can't see out of my swollen eye. I'm getting an ass chewing by the wing king himself and at some point he screams loud enough for all to hear, "Ain't you some kind of shit hot Sensei or something? How the f*** you end up with a black eye?" The name stuck after that. personally, I preferred WOWO.
