Faire un poisson d'avril

Meaning: To play an April Fools' prank on someone.

Literally: To make an April fish

Example: “Mes collègues m'ont fait un poisson d'avril en annonçant que le bureau fermait.” — My coworkers pulled an April Fools' prank on me by announcing that the office was closing.

Origin: Poisson d'avril first appears in 1466, in a work by Pierre Michault, where it meant a go-between who carried love letters; its use for the traditional April 1 hoax is attested only from 1691. Why a fish is uncertain: one theory ties it to the 16th-century move of New Year's Day from around April to January 1, another to April falling at the end of Lent, when fish was the required food.
