One of the items spoken of was a Ladies Bunco Night.  Now, I have had no direct experience with this, but as best as I have been able to discern, it is a floating craps game that requires the hostess to remodel and/or redecorate every room that any of the various participants may set foot in.  Also, it appears to require a catering budget that rivals some weddings.

Granted, this information came primarily from spouses of Bunco hostesses/players (who seemed to be exhausted from having to repaint the dining room) so it may be every so slightly exaggerated.

But, none of this actually answers the question of WTF is this game/pastime/obsession anyway?

If you know, please, do tell.
