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.
