It doesn't matter to me in the slightest whether you understand the meaning. You can fight the bike, stress out about traffic and generally have a ****ty time. Or you can learn that when you ride fixed, you relate to your bike in a much different way. You can adjust your riding style, learn how to work with your bike and your surroundings, and enjoy a oneness that you're not likely to find on any other type of bike.

To the OP: Practically, riding fixed essentially requires that you learn good pedaling technique, as it's nearly impossible to ride for any considerable length of time without understanding how to keep a fluid pedal stroke. Depending on gear choice, you'll be forced to either strengthen your legs(to get up hills) or learn to spin effectively(to get down them), which will make you a more effective cyclist in general.

Also, riding fixed without foot retention is incredibly dangerous, no matter what your skill level. I think it would be wrong if you weren't totally stressed out riding like that.
