Tongue in cheek

Origin

Imagine a Victorian drawing-room, where polite society often required a mask of decorum. To express a private jest, a hint of irony, or even a subtle mockery without breaking character, one might discretely press their tongue against the inside of their cheek. This silent, hidden gesture became a physical shorthand for an unspoken thought—a way to deliver a seemingly earnest comment while secretly signaling its playful insincerity. It was William Makepeace Thackeray, in his 1848 novel "Vanity Fair," who vividly brought this physical act into the English lexicon as a written phrase. He gave us "tongue in cheek," solidifying its meaning as a remark delivered with a knowing wink, not meant to be taken at face value, but rather enjoyed for its clever, underlying humor.
