An unusual verb

la sauce = sauce. Pretty straightforward, except the pronunciation is slightly different in French: the o sound is the same as in boring, at least in the northern parts of France. The southern accent would be very close to the English pronunciation.

saucer = to wipe something with a piece of bread, usually sauce left in a plate.
E.g. passe-moi le pain, je veux saucer = give me the bread, I want to wipe the sauce.
se faire saucer = to get soaked
E.g. on s'est fait saucer = we got soaked
