True Scotsman

"True Scotsman" is a humorous term used in Scotland for a man wearing a kilt without undergarments. Though the tradition originated in the military, it has entered Scottish lore as a rite, an expression of light-hearted curiosity about the custom, and even as a subversive gesture. However, the notion that no undergarments is the "true" or culturally authentic way to wear a kilt is a myth, as there were and still are many circumstances were it would not be appropriate. These include situations where physical activity or high winds might cause exposure to onlookers, very cold temperatures, and during seasons where swarms of biting flies are present.
