A fan of death rock. Not a goth, it's more like the step between punk and goth. The term comes from the name of a club, the Batcave.
Person #1: Look, it's a goth!
Person #2: No, it's a monochromatic punk!
Person #3: It's a batcaver, dumbasses.

The location in which a group of typically three or more people batman-it and get absolutely OYF for extended periods of time. Usually a hotel room, or garage, the batcave is complete with a billy, munchies, cigarettes, a television and couches with multiple burn holes in them. The original batcave has a Swastika marked on the brick wall.
"Wheres the reshn?"
"Oh fuck, I left it in the batcave"
"Latif's batcave or Saba's batcave?"
"TO THE BATCAVE!"
