1. The act of doing anything other than what you should be doing.
2. Wasting time; doing unnecessary things that will inevitably cause you to arrive late to appointments, work, the airport, and special nights out with your significant other.
You're thinking, "O.K. I just need to shape my eyebrows, pull some weeds from the lawn and give Rover a bath...It shouldn't take more than a few minutes."
Then you arrive late to the airport and miss your flight. You call to tell your friend that you missed your flight. Friend asks, "what happened?" You answer, "I guess I was piddle-paddling around to much this morning!"
