look up any word, like jamflex:
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.

Chris: Ohhh, I get it
