Usage notes
Used both as an adjective, to describe a restaurant which allows diners to bring their own alcohol (particularly if the restaurant itself is not licensed to sell alcohol), as a noun to refer to such a restaurant, and as an admonition in social invitations that guests should in fact bring beverages, as none will be provided by the host (similar to RSVP).
