Pressing the garage door opener just within range of home, and with perfect timing, in order to facilitate a 'slow roll' of your car inside the garage, thereby avoiding obligatory social interaction with annoying neighbors. As soon as the car is fully inside the garage, the opener is immediately pressed again from within the car to close the garage door, before the engine is even cut.

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.
