Handler
A Handler is an extremely fat girl that is usually also short and unlike a Dragon is almost always unattractive.  There may be no discernable waistline and she may also has a FUPA.  She could also be very broadbacked and no-necked.  For a girl to be a handler she must also be in the presence of her Dragon friend.
The reason she is a handler, is because you could easily invision her holding the chain of a dragon.  If she is by herself she could be considered a beast, or possibly a Troll, and maybe a short dragon.  
She could easily be seen as a female trucker.
The signal to your buddy that a handler is near is the same as that for a Dragon.  A motion of pulling a huge sword out of its scabbard like a knight.
Last night, my buddy got drunk and went home with this Dragon to slay her.  Her handler was was also there, and not only was she wider than she was tall she had there was no amount of alchohol that could get me to slay the Handler.
