The act of not holding back and putting your whole being into accomplishing a task, usually resulting in a state of awesomeness. Originates from the popular movie Black Swan starring Natalie Portman and Mila Kunis.
We won our scavenger hunt because we were running all around the city and we black swanned all the challenges.

Oh man, I totally black swanned my powerpoint presentation today. I made a bunch of crazy slides and inappropriate jokes, and the client loved it.
