Used to describe an action or area which is of poor socioeconomic value. Trailer trash, ghetto and houses with car parts, shopping carts are areas of LR.
Actions might be but not limited to using plastic grocery bags as handbags and claiming Twinkies as an ingredient in a desert will definitely constitute as an LR action.
Joseph: "Whats with the grocery bag Lynn"?
Lynn: "I use it as a hand bag so I don't get mugged in my neighborhood. I got some Twinkies to make my strawberry shortcake desert"
Joseph: " That's low rent"
