Earned his call sign Sh0tglass in his UEE academy years when, after a particularly rowdy celebration of finishing mid term written exams, one of his unappreciative bunk mates surreptitiously hid one off the many scattered items of glassware in his flight suit.
He failed to notice it the next day until already sealed in the cockpit of his Avenger for flight courses. When his instructor later reprimanded his poor performance on standard high gee maneuvers, and asked him what was the matter, he blurted out - over general comms - "It's this damn shotglass wedged up my arse!"
His academy mates never let him live it down.
Sh0tglass still managed to score 4 kills in mock combat that day, once he'd managed to shake that glass down to his boot.
