When your stuck in alot of shit, or are about to get your ass busted. It could mean escaping, whence you've allready been caught. It's about living, if your not on a cavale, then your stuck in prison or grounded. Real men make cavales. Real men live for a cavale.
Stefan: Yo Henry, I thought you got busted by them cops.
Henry: Nah, I made a cavale, and got outta there.
Stefan: Ah, Rah Digga.
