The Manx 

An event or occasion that is cool or exciting regardless of its number of participants, usually a concert or party. Named after short-tailed manx cats: even without a large tail (in analogy, a large following), still extremely effective.

There were only a few dozen people at the club, but after 9:30, that place was the manx!
