main line

Shooting up through the main veins in your arms.

It's lame that you can't main line that shit and you have to use your hand instead. Maybe you should take a break for a while.

Maine Coast Semester

An amazing experience where a group of students (38 for example) learn with their minds, hearts, and hands and find their ways through life together.

MCS was an amazing four months and I miss it very much.

pirates of the spanish main

A pointless high school sorority located in the southeastern region of the state of georgia. It is basically a group of catty, slutty, dumb high school girls who do nothing but party, get drunk, sleep around, get pregnant, and talk shit about other members behind their back due to being insecure about their own issues. They claim to be all "goody two shoes" and to help out the community. But this is all bullshit. Rush week for the pirates involves a series of stupid themed days in which the girls stuff their fat thighs into Winnie the Pooh halloween costumes that no longer fit from 4th grade (and yes they look like fucking retards). Of course they never include outsiders. Its always the doctor's children, the wealthy sea islanders, and the stuck up southern dance addicts who always make the cut. If you are an outsider from the north you might as well forget it. No way are you getting in. But then again, why would you want to be apart of this criticizing and self esteem bashing group of hoes anyway?

Anna- "Hey Jessica, wanna rush for pirates of the spanish main."

Jessica- "I'd rather gouge my eyes out"

main line

The main line is a place where there are tons of rich ass kids riding around in whatever car they want. whether it is the new BMW or Mercedes or maybe it's the mustang or STI. Merion Golf Club and Philly Country Club are the two most prestigious clubs and consist of nearly 100% WASPS. radnor valley is the country club that the jews like to hold onto because they wouldn't get accepted at either of the previous two. Malvern Prep, The Haverford School, Baldwin, Agnes Irwin, Shipley, Radnor, and Lower Merion are the preppiest schools around and are filled with very many rich kids. "nantucket" or "bermuda" red shorts are all over during the summers and no one would think about going out without a collared shirt on. if you don't wear J Crew, Abercrombie, American Eagle, or whatever else you aren't likely to fit in with the stereotypical mainliner.
Just like in all places there are exceptions and not EVERYONE is rich and snobbish like that; however, it is fairly prominent and behind every stereotype there is truth.

Let's go to the mall, get some starbucks, get fucked up, then tomorrow morning we'll go to my shore house in avalon or nantucket for the weekend. god i love the main line.
