Fedders house n. a cheaply made apartment building, specifically those featuring highly visible window air conditioner sleeves bearing the brand name “Fedders.” Editorial Note: This term is specific to New York City and is usually plural, Fedders houses, in an echo of naming terminology for government-sponsored apartment complexes, such as Walt Whitman Houses. It was coined by Victoria Hofmo, a community activist from Bay Ridge, Brooklyn. (source: Double-Tongued Dictionary)
