A community in Pittsburgh, PA featuring a mass of preppy kids going to school separated from the real world. The average Mt. Lebanon student can be found sporting a North Face backpack, North Face fleece (black for the popular kids), and a ralph lauren polo. Also referred to as "The Bubble" or "Lebo."
Mt. Lebanon is a great place to raise kids, but keeps them isolated from anything in the real world
