The Main Line is just about the waspy-est and jappy-est place around. The proportions have changed a little, but Junior League and Tiffany's are still there. The Main Line has some of the best private and public schools in the country, but it also has an underlying feeling of wealth and aristocracy, which makes it a bad place to live. Unless you yourself are rich, you'll be completely snubbed on the Main Line. Even the Beverly Hills girls aren't so obnoxious.

worst. place. in. the. world.

unless you're rich and don't give a shit about anybody but your socialite friends, even though you talk about them behind their backs anyway.
i have been forced to live on the Main Line by my parents, which is why i'll probably end up in therapy someday.

(n) The front-running leader(s) of an industry; not the imitation spin-offs. Reserved for the select few whom others try to imitate albeit never successfully. If you are not mainline you are hopeless and should probably just quit what you do, now.

(adj) Describing an action that would only be done by someone/something that is mainline.
Guy 1: Why does that guy drive such a shitty old car if he's a lawyer?

Guy 2: He must not be mainline. If he were, he would drive a BMW 5 Series.

Guy 1: Lebron James is overrated.

Guy 2: Seriously?! He is the most mainline basketball player of this generation.

The Main Line is just section of rich people who think that they are better then other people. It is also a place were you can see some of the most impationt people in the world for driving, buying, and even talking! If you are a "Main Liner" then you are most likely wealthy and live in a massive house with 5 bathrooms or you live in an apartment with the delux put in it. A person who lives in the Main Line also may think that he/she is a real cool kid and likes to wear the following:
1. a polo (aka collared shirt)
2. a college hat
3. baggy sweat pants
4. a 150 doller shoes you got customised
5. a gucci wallet

A Main Liner also likes to listen to either rap (typiclly the best known rapper) or the newest alternative rock band that is played on MTV.
You can consider a Main Liner a prep or either a goth.

Your significant other; a spouse; your principal partner of many.
"I won't be kickin' it with y'all tonight, I'm takin' Main Line to the Red Lobster."

To watch a large amount of a geeky television show, episode after episode, for a long period of time. A season of Buffy in two days, for example.

Similar to marathoning movies or chain smoking, but more geeky.
"I just mainlined the first 3 seasons of Angel"

"I'm going to go home and mainline the LOTR movies."

"Wheres Ferg at?"
"Oh, hes at home, sitting in the dark, mainlining Simpsons episodes"

The main line is a collection of suburbs containing of douche bags that THINK (and only think) that they are better than the rest of the world, and they like to flaunt it all the time. They pop their collars, don their Gucci, and D&G, shop at Banana and J. Crew full price, and love to repeatedly use the word BEST in their sentences. (aka "ACME bakery makes the BEST cookies in the world" or "WaWa is the BEST place to go get a hoagie at midnight" or "Going to Ocean City is the BEST time ever") It's just so sad that main liners heads are so far up their asses that they all can't even see straight. There is more to life than looking good and flaunting where you're not the only douche bags who live in wealthy suburbs, ya know?

Most inhabitants are "old money" (aka Grandpas who made their fortune and moved to PA). All the others, like people that live in Paoli, Wayne, or Berwyn, etc. are all either living off of there old relatives' fortunes or pretending to be what they're not. Some live in big houses and that's all they can afford; others choose more modest living quarters so they can survive financially. Either way, they ALL can say that they live on the "main line," and that's really all that matters to them, in their egotistical, superficial minds.
Main liners use the words "main line" as an adjective! (aka "Suzy is sooo main line.") Amazing isn't it?

Statistically, I grew up in the wealthiest zip code in the country, 60010. However, I don't brag or flaunt that because if I did, well, let's face it I'd be a douche bag. And I'm not a douche bag. Main liners....are douche bags. so sad.
