fu-ling

The action of having one last night of (fucking) sex with a friend who is getting married to someone else, solely based on the fact that you know you will not anymore after they are married. (fling)

I know your wedding is in two weeks so I will meet you next Friday for one last fu-ling.

I was sad to discover my friend got married in a shotgun wedding in Vegas and we didn't get to have a fu-ling beforehand.
