The event began in 2002 in New York City with seven members of the improvisational group, Improv Everywhere, known for their flash mobs, boarding the subway without trousers. By 2006, 150 people had joined the fun, feeling the draft as they rode the train without trousers.
'The idea behind No Pants is simple: Random passengers board a subway car at separate stops in the middle of winter without pants. The participants behave as if they do not know each other, and they all wear winter coats, hats, scarves, and gloves. The only unusual thing is their lack of pants,' Improv Everywhere's website reads.
今回取り上げるのは、“the draft”（cf. Br. 綴り draught ）です。
ただし，“feel the draft”で，「歓迎されていないように感じる、冷たくあしらわれているように感じる」（"to sense that one is being rejected; to sense that someone is cool toward one, possibly for racial reasons"--McGraw-Hill Dictionary of American Idioms and Phrasal Verbs）という意味もあるのですが，ここではどうでしょうか。(ninetails)
