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.

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.

I do beleive the term farting licking has something to do with the licking of farts,but I digress,a fart thusly licked by a person has been fartlicked and the person who has licked the fart will be deemed a fartlicker,the psychological need for a person to lick farts is a conditon known only as fartlicker syndrom.not much is known about this condition,where it came from,if it's airborn what have you,but one thing is certain there is no cure ,and treatment involves the deprivation of farts,where,the fartlicker is placed in a house will lots of air fresheners and industrial airfilters to suck the farts out of the air,if you are a fartlicker there is hope,but you must seek treatment
