A schmuck of a model, most often a fashion model. She's conceited, pushy, lacks an awareness for the meaning of "punctual", often is a no-show, and usually demands more money than she's worth. Other girls may refer to her as "skinny bitch
" or "model whore
", even though the latter is not entirely accurate at times (but most often it is).
A schmodel's diet consists mainly of vodka and cigarettes.
A schmodel may also be male. But male fashion models are harassed enough as it is, so the above description is for the female variety of schmodels. However, the likelihood of a male schmodel being referred to as "skinny bitch" and "model whore" is just as great as that for the female schmodel.
Photographer: "First she showed up three hours late for the shoot, and then that damn schmodel demanded I get her an iced chai latte with exactly four ice cubes (no more, no less) before she'd even sit down for makeup!"
