P.L.V.

(abbr. pour-la-vie): For ever-and-ever. (Like 'SWALK': Sealed-with-a- loving-kiss, this lowbrow amorous pledge is very much an open secret and could be found up to the 60s carved on tree-trunks with a heart and the initials of the plighted. A few ill-advised males might still sport it tattooed on their forearms or hairy chests!)
