I just googled " easy victor" and it came back with this from another forum
Easy Victor is, I believe, from the olden days. (That's what it was when I started in the 80s.) Used to be thought that a "code word" would alert the FA crew, but not alarm passengers.
Now I think there has been a major shift in thinking. Direct, unambiguous communication to FAs and passengers is best. Thus "Evacuate!" or "Cabin Evacuation" is the preferred signal.
