"Easy Victor" is the evacuation command at many US carriers. It does not mean an evacuation is imminent; it is the actual command. It is used in cases where an evacuation alarm is either not present of fails to function. Its purpose is the give the cabin crew time to initiate the evacuation before everyone else starts running for the doors. I suspect that if you use the plain language term "evacuate" (as my most recent airline did), it is possible that a flight attendant will not have time to evaluate the usability of the exit before a passenger starts to open the door, particularly in cases where he/she is responsible for both doors cross-aisle.
