The practice of dumpster diving around University of Pennsylvania facilities and Dorms.

This activity is also based of the stereotype of rich and financially stable people being extremely wasteful. Throwing out a red ring of death xbox 360 instead of ebaying it or attempting to fix it is an example of the wastefulness that can result in a Penn Christmas
