east infection
A disease that hits resort towns when people from the East Coast move in and ruin everything. They take over the town, make everything expensive, and act like they're better than everyone else.
My hometown got 'east infection' when 50 new people from New York moved in and bought all the houses.
The local diner went out of business because of 'east infection'.
My neighbor now speaks in a fake New York accent and thinks he's cool.
