jaypan fan

From lyrics of "Jackson" probably referring to a Japanese Fan which a distinguished lady might use on a hot day in the old South.

June Carter and Johnny Cash banter in the song about a hot and cold marriage. He's going to Jackson to "mess around," and she says to go ahead and make a fool of yourself.

a "jaypan fan," Japanese Fan is a Geisha accessory who uses it for more than just cooling but as an expression of shyness or being coy or in a fit of rage shutting it up with a flip of the wrist not unlike flashing a switchblade
