future tripping 

To worry/freakout about the future instead of enjoying the present.

*Wind Blows*
Max: Feel that? It's gonna be really cold later!
Jack: Dude, stop future tripping and enjoy the breeze!

Future Trippin 

When your significant other is tripping about events that are either a) hypothetical or b) occuring in the future or c) will never occur.

I.E. "Yea, it was crazy, dude. That girl was future trippin!"
