Main Line

Definition

The affluent Philadelphia suburbs historically anchored by old-money families who arrived via the R5 SEPTA train line, characterized by generational wealth, Catholic heritage, elite schools, and an unshakeable belief that new money will never quite measure up. A dying way of life where inherited social status matters more than actual economic acumen.

Example Usage

Everyone at that country club went to Main Line private schools and still won't let the tech millionaires join.

^______________^

An exaggerated text-based emoticon featuring an extremely wide smile, used to convey either genuine overwhelming happiness or thinly-veiled sarcastic innocence when you're clearly guilty of something. The length of the underscore indicates the intensity of either your joy or your obvious lying. It's the digital equivalent of a kid with cookie crumbs on their face insisting they didn't raid the cookie jar.
