Let’s face it, as the whole Wonderbolts nickname thing is borrowing from the tradition of Military aviators giving each other horrible callsigns, any name playing off a bodily waste malfunction, sexual indiscretion, catching an STD, or accidentally killing a harmless animal would be entirely in character. A few of my favorites are: Spitroast, Shitrocket, Crotchfire, or GATS*.
