'clear the floor' is a term often used in jail/prison. Corrections staff call out 'clear the floor' to initiate a lockdown. When 'clear the floor' is called, all the inmates within earshot are to sprint to their cells, enter it, and close the door behind them. This is used during situations, such as fights, in which the corrections staff need to make sure all the inmates are secure.
