“裤子，内裤，”1840年，参见 pantaloons。这个词最初仅限于粗俗和商业用途。
I leave the broadcloth,—coats and all the rest,—
The dangerous waistcoat, called by cockneys "vest,"
The things named "pants" in certain documents,
A word not made for gentlemen, but "gents";
[Oliver Wendell Holmes, "Urania: A Rhymed Lesson," 1846]
口语单数 pant 自1893年起被证明。wear the pants “成为家庭中占主导地位的成员”始于1931年，也用于 trousers。by the seat of (one's) pants “凭借人类本能”始于1942年，最初用于飞行员，可能有通过引擎振动等感知飞机状况和情况的概念。caught with (one's) pants down “被发现处于尴尬状态”始于1932年。
