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.
