A fauxstie (fo-stie) is a person who acts like a coastie, but is not from the coast. Many of these people are from rich north Chicago and north Milwaukee suburbs. Unfortunately, they are as displeasing to be around as regular coasties.
Chris: Damn, look at the girl with the uggs and the northface. Stupid coastie...
Phil: But wait, shes from Chicago, so shes a fauxstie.
1. One who poses to know all there is to know about fashion; 2. a self-proclaimed fashionista with no real sense of personal style; 3. A serial style copycat who wouldn't be able to get dressed without the latest issue of InStyle or Us Weekly.
Use faux for short.
The sales associate at Nordstrom was such a fauxshionista!
All the fauxs are anxiously waiting to mimmick Carrie's outfits from the Sex & the City movie.
