Someone of whom is very large (read: fat) and possibly ugly, yet believes themselves to be really attractive and so dresses to show off their body. Imagine a really big girl, wearing a very short skirt. If you've just turned away and feel like you're about to puke at the sight/thought, then you have yourself a Pukeasaurus.
Dan: Hey Joe, check out that chick!
*Joe turns to look*
Joe: Ah dude no! Such a pukeasaurus.
*Joe turns to face away from her, sickened by the sight*
