The most important thing you can have. Without fitness, your a fat homosexual who sits around all day watching movies on your computer and eating cheezits. To be fit is to be god.

Can also be used to replace words like "good", and "skilled"
Guy 1: "Wan't to go get something to eat?"
Fitness Guy: "FITNESS!"

Guy 1: "I think we should take the bus to the movie"
Guy 2: "Nah, that wouldn't be very fitness"
Get the fitness mug.
