treadmilk 

treadmilk is created when sweat from the person on the treadmill mixes with their foot grease, and gets caught in the treadmill. Later, it is then turned to sludge,{which is the treadmilk} and once consumed it creates a healthy diet of treadmilk which is incredibly healthy!

Guy 1: *phew!* it takes me forever to get slim with these regular diet drinks.
Guy 2: well that's why i used treadmilk!
{PS don't actually try this}
