I first heard my cousin Cory using this term a few months ago. Her intelligence is near non-existent so I presume she was not the first to come up with this term. I am unsure of its exact meaning but you get the idea.

It is a running term meaning that, after you warm up and have been jogging for a few minutes, you run hard for one minute, slow for one minute, hard for two minutes, slow for two minutes, hard for three minutes, slow for two minutes, hard for two minutes, slow for one minute, hard for one minute, slow for one minute, and then you start over.

Unfortunately, it is not an amusing definition.
