I would imagine he watched a 1970s/1980s movie the night prior where the phrase was uttered.
If you go back over the past two years and identify all of these odd statements....they all relate to movies he watched the night prior. ‘Pony soldiers’....remember that one? 1952 cowboy western that he probably watched.
We ought to sit down and catalog all of the comments and relate them to movies.
Maybe soon he’ll be heard to blurt out “Sufferin’ succotash!”
Interesting idea…
