Shirtcocking is the curious behaviour of a man, usually middle-aged or older, wearing nothing but a T-shirt at Burning Man. It is considered an inexplicable fashion faux pas by many, but others are quick to point out its nature as an act of radical self-expression. Those opposed usually explain their confusion thusly: “Either be naked, or don’t. Why the T-shirt?!”
Popular synonyms include Donald Ducking, shirtclamming (for women), and Daisy Ducking (also for women.)
The antidote to shirtcocking is a mythical invention known as The Pants Cannon, which shoots pants at shirtcockers.
