Must have been a slow week in The Villages, or else this is one of those urban legends.
Visited my sister and BIL down there a few months back for nearly a week. Saw about a zillion golf carts, along with regular cars of course, didn’t see a single loofah. YMMV of course, but it’s viewed as kind of a joke down there, at least among my sister and her friends.
Maybe your relatives don’t partake of that lifestyle, it’s likely a minority of the people down there riding around with loofah’s on their vehicles advertising what type of swinger they are, assuming it’s true at all.
