A nickname earned by a Carleton Engineer that is inscribed on their flightsuit and/or F.I.T shirt. Callsigns are usually given to commemorate outrageous acts during frosh week, but can also be based off a recurring personality trait, or something completely irrelevant. Callsigns are traditionally regulated by the flightsuits, the self described militant wing of the Engineers at Carleton. Callsigns is also a drinking game where the participants must remember the action and callsign of the person before and after them in sequence, with varying difficulties as the "level" of the game increases.
Sebastian: "Why does Chris have the callsign "Sexbot"?"
Luke: "Well, he created a robot costume out of pizza boxes, made a giant pink cardboard penis for his costume, and walked around the market like that for the night."
