A large, ungainly girl (tall, well built than
fat) who appears a bit dumb and/or clutzy, not particulary attractive. Or perhaps a girl who is a bit too
big to be completely feminine, like
Kimora Lee Simmons. Basically a girl whose physical presence is vaguely reminiscent of that hulking, slow-witted animal, the moose, which lacks the grace of something like a stag.
