A lap ance is a specific type of sex dance offered in some strip clubs or (somewhat more formal) gentlemen's clubs in which the patron is seated, and the dancer is either in immediate contact (contact dancing) with the patron, or within a very short distance. Depending on the local jurisdiction and community standards, lap dances can involve touching of the dancer by the patron, the patron by the dancer, neither, or both; the dancer may be naked, topless or fully clothed. Variant terms include couch dance which is a lap dance where the customer is seated on a couch, and bed dance where the customer lies down. A block session (usually half an hour to an hour) can be booked in the champagne room, where the dancer and the patron talk in an intimate setting and drink champagne together. The male/female might perform lap dances too, depending on the patron's wishes.
