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.
Everyone that has given a definition to this word, including me for wasting my time. Mainly used because of the idiocy received just by seeing all your spelling errors and lack of original usage of the word.
