A "Gigantoslagasaurus" is a half reptile, half human abomination of a woman. The natural habitat of Gigantoslagasaurus varies from shopping malls to McDonald's to horrible night club chav magnets. A "Gigantoslagasaurus" is easily identified by her slimly gross reptile features, a weight of over 15 stone, and dress sense of a Barbie doll. The most heinous feature of a "Gigantoslagasaurus" has to be her failure to recognise she is an ugly fat bitch.

Literally everyone, ever. Including the writer of this definition.
