@Mame,
That you and Roger have never heard of it is hardly the test, Mame. It's not up to you two to be the arbiters of what's what for language.
Contrex and Laughoutlood both gave possible meanings, as did I. Roger allowed that it could have a meaning then he seemed to get his hackles up and changed his mind. Rocky simply said, "I dunno", allowing that this grammatically constructed sentence may well have a meaning to th person who spoke it and those around that speaker.

Channeling dear old dad? Other people's communication is often opaque. I could give you countless examples where you would be baffled, OR, if you had a real interest in understanding language instead of relying on your old saws, you could remember times in your life when you came into a group having a conversation, you listened a bit and then said something like, "What the hell are you guys talking about?"
