Top definition
A bar/club that occurs in a residential home. The primary function of the house originally was residence, but because of its popularity has become a bar/club that regulars visit even when the owner of the home is not home. It is not a commercial venue, but a place that everyone consistently gravitates to because of the bar/club activities that take place there 24/7. Traditionally cubasnis are designed to accommodate bar/club activites and have pong tables, bars, lounges, black/strobe lights, stripper poles, etc installed.
