The Batcave: the vary first goth club back in the early 1980's, originally intended to play darker glam rock & new wave.

the term batcave is also used to refer to the music that was played there as well as anything that sounds like it(predominantly dark bass-heavy glam with elements of horrorpunk, new wave, & postpunk) as well as other goth clubs hopefully that still play actual gothic rock rather than just dark electo, EBM, pop, or metal.

the term Batcaver often shortened to just Bat may be used at times to refer to people who go to these clubs or are fans of such music.
the Bat cave was demolished and turned into an apartment complex, but it's spirit is still undead
