The act of masturbating behind a dumpster while on a break at work. Often done in order to relieve stress or "clear" one's thoughts, such breaks are taken by employees in nearly every career field. However, studies show that the majority of cases occur in high-stress jobs such as: short-order cooks, security guards, carnival ride operators, janitors, and air traffic controllers.

The dumpster break is signaled by the universal sign of a single sock hanging over the side of the dumpster, warning others to stay clear.
