Girls from the coastal areas of the United States, who for some reason decided to flood the University of Wisconsin - Madison. Very easy to spot, owing to their overuse of: Uggz boots (even when it isn't cold or snowy), large sunglasses (even when there is no sun), messy ponytails (for that "I just completed the walk of shame and didn't shower today" look), and anything North Face, typically the Denali jackets or knee-length down coats. They also like to wear stretchy black or maroon pants bunched up around the tops of their Uggz. During the winter, Coasties can be identified by their bright orange skin- they are notorious over-users of tanning booths.
God, she's such a coastie! Look at her boots- it's May! What is she doing in Wisconsin???!!!

Coasties are the random students who choose to attend midwestern universities, such as UW-Madison, that come from the coast. Most prevalantly coming from New York or New Jersey.

Coasties usually keep to themselves and are stuck up and lack the humility that most midwesterners have. They voluntarily choose to segragate themselves from the population. Don't bother trying to talk to them, as they will look down to you. They usually take over the school's greek system, keeping us normal people out.

The girls tend to act pretty dumb and use the word "like" alot. They dress really slutty in their black spandex and v-neck shirts. Northface jackets, big sunglasses, scarves, and ugg boots are a must.

The guys are obsessed with the Yankees and the Jets and are overconfident in their abilities with women. Most of them are douchebags.

More recently coastie has become more of a social definition rather than a geographical one. Some people in certain Chicago suburbs have also displayed the coasite trait. This group is called fauxsties. To be fair, there are nice people from the coast with deveopled social skills, but sadly they are a dime a dozen.

The term coastie or coasty (more often heard and seen as the plural coasties) is used in Midwestern U.S. universities such as the University of Wisconsin-Madison to denote students who come from outside of Wisconsin, mostly the Chicago area and the Coasts. The term is also more loosely applied to in-state students from other areas of Wisconsin. Although the most general use of the term denotes only the origin of these students, there are often implicit or explicit associations that use of the term can evoke. One is that coasties do not pay their own tuition because they come from socioeconomically privileged families. Other associations include living in private residence halls and membership in a fraternity or a sorority. Other associations are fashion-related and are therefore more ephemeral. As of 2005, coastie fashion consists of Ugg boots, The North Face jackets, plain spandex and over-sized sunglasses. The term has become increasingly widespread since the Milwaukee Journal Sentinel did a story concerning the differences and tensions between coasties and students from the Midwest.

Name given to members of the US Coastguard. They are known in towns with Coastguard bases for their pirate-like behavior of plundering the town's resource of women and local bars or taverns.

I have been personally told by many of them that they do not like mere civilians calling them that and many of them say that they were the ones who began calling themselves that.
"Kat really likes those Coastie guys. It must be the hot navy blue clothes they wear for work everyday."


"The Coasties really used to come to our town and act like a bunch of pirates by plundering the local bars and taking over the local women. It isn't so much now since the new boat and it not needing as big a crew as the old one"

A person, typically from the Gold Coast, Australia, who has a relaxed and carefree demeanor and enjoys engaging in activities that do not involve high standards of etiquette nor require more than limited mental activity. A subcategory of bogan. Coasties will typically have more money than class.

Coasties will usually dress in surf labels and thongs during the day, and wear minimal clothing at night regardless of the temperature, preferably in loud colours or with offensive prints and/or slogans.
"How about we cruise around town in a white hummer tonight drinking vodka and then hit up Shooters? I'll wear my Gasp dress with my gold heels and my sparkly Guess bag" "So coastie, ay!
