3.
The act of sitting in ones room or bed completely instilled in darkness much before the time they plan on going to sleep. One who bat-caves often keeps them self occupied with a computer or videogame to play on. Music is not typically listened to by the bat caver and social conversation does not usually take place. It is described by common bat-cavers by relaxing, or "me time" to settle down. Bat caving is usually followed by whacking off and then going to sleep.

1.
Asocial behavior, most often seen in the suburban United States, in which people will enter and exit their house or apartment by way of the garage, thereby eliminating any unwanted social interaction with neighbors, passers-by, and the outside world in general. Staying in one's vehicle until entry or exit from the garage has been completed is key to effective batcaving, as is having an automatic, remotely-openable garage door. Living in a gated community provides an additional level of batcavability.
Did you hear about that woman in the news? She lives around here!

How would anyone know? Out here, neighbors go batcaving in and out of their place and we never see them. Except when they mow the lawn. And everybody pays to have that done anyway.
