Batman factor
 n.

   1. An integer number representing the number of items hanging from a
   {batbelt}. In most settings, a Batman factor of more than 3 is not
   acceptable without odd stares and whispering. This encourages the
   hacker in question to choose items for the batbelt carefully to avoid
   awkward social situations, usually amongst non-hackers.

   2. A somewhat more vaguely defined index of contribution to sense 1.
   Devices that are especially obtrusive, such as large, older model cell
   phones, "Pocket" PC devices and walkie talkies are said to have a high
   batman factor. Sleeker devices such as a later-model Palm or StarTac
   phone are prized for their low batman factor and lessened
   obtrusiveness and weight.
