A type of exercise usually found in military recruit training where individuals pair up, with one performing an exercise such as pullups, burpees, or pushups, continuously while the other individual has to run to fixed object and back, where they then switch places and continue. The longer the running individual takes to complete the distance, the longer his buddy has to exercise.
Drill Instructor: "Have you really stopped running while he is doing pushups, you really are a buddy fucker!"
