Batmobiles
from TTL french expression : Blindés d'Assault Terrestres Mobiles or officially B.A.T.M. English speaking soldiers decided to call them Batmobiles as BATM was difficult to use as a "fun" name.
The drivers of the Batmobiles, usually called themselves Bats or Batmen, after a drunk driver said "I am the man who drives a bat, I am a batman". The first english Batmobile model was named Dracula. Mephisto and Belzebuth models quickly followed, until the use of demon names were considered too sacrilegious and blasmephous.
