running full-out 

To run like Britney Spears (presumably when she was attractive) while being Neil Peart.

“Oh my god! He runs faster than Britney Spears! And she was running full-out!” - Originally uttered by an anonymous elderly female security worker for a Rush concert. This version of the quote is the one told by Mr. Neil Peart during an interview after some show, or something.
