Laugh up one's sleeve
Meaning
To secretly feel amusement or triumph, often in a way that is hidden from others.
Origin
During the 17th century, fashion dictated that many garments, particularly those worn by the affluent, featured voluminous, wide sleeves. These flowing fabrics weren't just for show; they offered a convenient, discreet curtain for various social maneuvers. When someone wished to express amusement or even contempt without openly offending, a simple gesture of raising a hand to the face could conceal their true reaction behind the ample folds of their sleeve. This physical act of hiding a smirk or a chuckle evolved into the idiom, capturing the essence of secret, often suppressed, mirth.
Examples
