An area of BalCo, Maryland which was once marshlands until it was drained and developed, resulting in White Marsh mall and the Avenue, a hangout full of teenage wigger wanna be "gangstas" who think their hardcore.
They like to take their "bitches" to the mall where they loiter and try to scare people.
A: hey you going to white marsh?
B: hell no! only if I want to see a wigger trash parade.
Well basically it aint white no more, all these thugged out black kids come up to avenue like they run shit, it aint white marsh no more its black marsh.
Nigger marsh is what it became
