Future fun is the fun you are not having presently, but will have when you tell people about it.
Bill: Dude, I heard you went to Hawaii, how was it?
Bob: All i did was sightseeing. The airport lost my luggage and I spent the entire week in the clothes I went there with.
Bill: That sounds like it sucked.
Bob: Yeah, but it's future fun!
