Put simply, “while trying to grease-up the Space Stations creaky solar-panel-rotating gears, some grease accidentally squirts into the toolbag, and astronaut H.S. Piper loses her bag while trying to clean it up.” Video after the break.

(In case you are wondering what happens if an Astronaut floats away, note the large white backpack on the back of the spacesuit; this is known as the “SAFER” unit and is a jet-powered backpack to allow the astronaut to float back to the station during U.S. spacewalks. To the best of my knowledge, it has never been needed.
