A large, gay dance party, something like a gay version of a rave, but with a gay-oriented music selection (usually pop, progressive house, and tribal). Events are well-promoted, publicized, advertised and organized, are often attended by thousands, can be big charity fundraisers, and are usually expensive to attend.
Since each circuit party occurs on a specific weekend and in a specific city once a year, and there are many parties on "the circuit", travel and planning are required. Travelling from party to party becomes part of a circuit boy's lifestyle of travel, networking and partying.
Some examples of circuit parties: White Party in Palm springs (April), Black Party in New York (March), the Black and Blue Ball in Montreal (October), the Blue Ball in Philadelphia (January).
These are often all-night and multi-day events, and party drugs such as ecstasy, GHB, ketamine and crystal are frequently taken by partygoers.
It's only August, but circuit boy Dave can't wait! He has already booked his hotel for his favorite circuit party, White Party Palm springs next April.
