A French phrase used as an interjection which literally translates to "that's the worst" (pronounced 'Sah Say luh PEER'). Can be used to express regret or disappointment, or to show anger.
Boy - Wow, my neighbor stole all my dog's puppies and put them in a sack and beat them against the wall until they were all dead.
(Idiom) Literally translated, means "It is the life". Better translations lead to "That's life" or "it's life". Basically shut up and get over it, used as a puit down. The best retort to this is "C'est la guerre", which means "This is war".
*A and B find A's car being keyed by a person known to be a local trouble maker*
