A person from Westbrook, Maine. He or she lives a low-brow, broke ass lifestyle, but they wear it like a badge of honor. 'Cuz nobody likes a snob anyway!
Person 1: I'm from Westbrook.
Person 2 (most likely from Falmouth, ME.): Dude, ew. You're a brook rat?
Person 1: Screw you, snob.

Someone from the town of Westbrook, this is someone who likes to get fucked up. Including but not limited to drink alcohol, smoke butt's, smoke weed, smoke crack, blow pill's, blow anything they can get in their nostrils.
