In the South Island, the self-same holiday homes of all genera are called cribs.

So *that's* where the ebonics word came from. (But in South Central LA, where it's used, one's crib is his home, not his vacation villa).

And how do you pronounce bach(e)? Like batch? Has it anything to do with bachelor/ette? Perhaps because it is where one flees when he suddenly finds himself single again?
