Actually, just after posting I managed to recall it. I didn't read but heard it the first time, too, from someone who went for a summer work as youth camp overseer to Massachusetts. So it is probably spread well beyond trailer park land.

   Many years ago, some friends of mine and I decided to have some fun with a newly-arrived (to the U.S.) foreign guest student.  Our plan was very simple.  We were going to explain that, in America, people generally ate Chee-tohs (tm) [Frito-Lay's brand] cheese crisps with everything ---at breakfast, lunch and dinner---except, of course, in certain snobbish fancy places or where they had some reason to depart from their usual customs, as when, for example, many natives might shy from admitting to a foreign visitor the virtually universal practice of having Chee-tohs with everything.   Hence, we were letting the visitor in on the inside dope, which otherwise he might not discover without our help.

   And, of course, we made sure to have plenty of Chee-tohs on hand and to eat them with everything, till our scheme was exploded.
