Tremper son biscuit

Meaning: To have sex (vulgar slang).

Literally: To dip one's biscuit

Example: “Il ne cherche pas l'amour, il veut juste tremper son biscuit.” — He's not looking for love; he just wants to get laid.

English equivalent: To get lucky

Origin: Vulgar slang for having sex. The biscuit is the long, finger-shaped sponge biscuit (biscuit à la cuillère), chosen for its shape, and dunking it is a food joke of the same kind as many other sexual euphemisms. Blaise Cendrars uses it in 1946; its first appearance is not documented.
