"Urban myth" comes pretty close. Or, you can try "wives, old or new,
almost never talk about green stains in gum, and they never make up
tales about them."

Hi John,
Isn't there another expression besides "old wives tale", something
arguably more politically correct? How about old boys' something or
other... Actually I think there isn't, probably for lack of trying.
(There's an expression something like bubba meisser, but I think that
means old wife too.)
