Subzilla
Arrogant fat women who get off on entering a subway train and scan for any tiny opening between people on a bench (most often next to skinny women which they are jealous of), then proceed to squeeze their huge ass into said tiny space shoving over passengers on either side.
See definition. You'll know the nightmare Subzilla right off especially if you live in NYC, are skinny, and ride the subway.
