Back in my Navy days nicknames/radio callsigns were usually bestowed by the pilots in your first fleet squadron. Unless you already had a fitting one.
One morning soon after I'd reported to the squadron our Intelligence Officer, who was very short and therefore christened "Inch High Spy" decided to enter me in a National Enquirer "Biggest Nose In America" contest. As he approached me with a measuring tape and a maniacal grin I objected that another new guy pilot obviously had a much bigger nose than me. His was curved, mine was straight - his HAD to be way bigger.
"I'm entering him too. Stand still, dammit!"
This travesty, and the commotion that ensued while he was trying to measure me, led to Inch High Spy conducting a contest to give me a call sign related to my alleged big nose. The other guy's even bigger nose was forgotten. I wasn't too upset because "Snail" had been my nickname/callsign for over a year while in the Training Command and, well, who wants to be a snail? It had followed me to the fleet and I was getting used to it. I even had started a collection of snail art - figurines, carved wooden snails, etc. Snail had been imposed on me by two Marine Corps instructor pilots during my first formation flight briefing because they'd heard I went to a hippie college where the mascot was a Bananaslug, which was true. They immediately had rejected my wannabe fighter pilot suggestion of "Slashing Avenger" when they asked me what I'd like to be called on the radio. "Slash" would have been pretty damn cool. My Marine Corps next door neighbor in married base housing and fellow student pilot for that formation flight had tipped them off.
The contest lasted more than a month, with lots of callsigns written up on the Ready Room white board for consideration. We were forward-deployed in Japan, flying off the USS Midway, so somebody immediately put up "Fujiface". Rudderhead was next, which was appropriately nautical. The mental image of turning my head while swimming and veering wildly off to conk my head into the side of the pool amused me, but call signs have to fit into tense radio transmissions between wingmen. You never heard "Maverick break left, break left! Bogie seven o'clock, three miles!" So Rudderhead, like Maverick...way too long and sure to get garbled. You heard, "Mav! break left!"
Would "Rud! break left!" have worked? With my luck Rudderhead would have morphed into Rude. Well, that might not have been so bad...
Hosenose. Dumbo. Snot. Booger. Pinnochio. Blowfish (I'm like, Blowfish? I don't have fat cheeks), the candidate list grew and grew. If you can imagine it it probably got up there. Within hours Inch High, delighted by the participation, created a "Daily Changing Call Sign" kneeboard card. He had a different nickname/callsign for each day of the month. After consultation with the kneeboard card I was referred to, and addressed, by a different callsign every day. Even the squadron CO made a big deal about consulting the kneeboard card.
Growing up in San Francisco I'd read about white shark attacks often enough to develop something of a phobia about them. And, maybe, perhaps, my joining the Navy had something to do with facing that fear - I dunno - but today my being glued to the TV every summer during SharkWeek isn't helping. I'd mentioned my concern about being turned into shark poop after ejecting into a feeding frenzy to a squadronmate. He entered Finface. Thankfully he didn't enter "Poop". You'd think I'd learned not to divulge things.
Shortened to "Fin" it may well have won Spy's contest, except someone then yelled out, "I got it! He's got a horn on his face! He's ugly, slow-witted, has poor eyesight, has a squatty-body, and is stubborn as hell! He's Rhino!"
In signing up for forums it seems many people like the handle Rhino. Finface became my shark-phobia induced fallback.
I pretty much answer to anything.
