Girls who can be found at pretty much any college campus specifically, Michigan State University, who typically wears the standard coastie unifom: leggings, v-neck tee, north face denali jacket, ginat sunglasses, and ugg or emu boots.

These girls are proficient in multi-tasking, especially on their blackberry or iphone.

Coasties seem to always be having some sort of Starbucks, Beaner's, Sparty's coffe, or a travel mug in hand.
"Look at that coastie over there - why is she wearing shorts and flip flops with a fleece?"

A girl NOT from the coast but who acts, or tries to act, like she is. Typically flaunts her one token Juicy sweatshirt and thinks she is the shit because she has Uggs and a $300 Michael Kors watch. Really, isn't though.
Ignore her, she is just a typical non coastie coastie bitch.

A Coastie bump is the art of sniffing your MDMA through your nostrils, as opposed to the orthodox method of swallowing in cap form or stirred through your drink. The bump can be done using a spoon, straw or other utensil but more traditionally is done on the base of your thumb in a clenched fist. A Coastie bump is best served when an instant boost in dancing power and happiness is needed mid-rave.
JT (mid rave): Hey Travis, How you feeling?
