Prestalgia 

To predict the nostalgia that will come from something that hasn't happened yet or that is happening now.
Like missing someone before they're gone.

- You know, once you guys are living in London, I'm gonna come visit you and we're gonna look back on these years and say those were some pretty awesome times.
- Ya, I think I miss this already.
- Me too.
- Aw, I can't take all this prestalgia.

Prestalgia 

Prestalgia is a similar feeling to nostalgia. It's not for a time that's been in the past but rather in the future. You already feel nostalgic about these moments and you know that you'll be nostalgic about them long after they've passed. You can also be prestalgic about a big dream.

"Bro I feel so prestalgic about the trip to this pacific island. It will be something so special. Flying there in that small plane during sunrise, looking at the stars with my girlfriend or eating breakfast at the beach."
"Man that even gives me chills"

or

"If I'm done with university I really wanna do a trip through south america in a little VW Van. Just travelling and experiencing all these beautiful scenerys. I feel so much prestalgia thinking about that.

pretaliation 

Getting your revenge in first.
Do unto him before he can do unto you, if you like.
A guy looks at you nastily across a rugby scrum; next maul, you tear his ear off, before he does the same, or worse, to you. You have completed pretaliation. Anything he does after that is retaliation, which referees always come down on harder than on the original malefactor.

"Did you see Tonto get his pretaliation in on that mean-looking winger?"
"Yeah, he'll be counting his ribs for a month! What a kick! Bet Tonto keeps out of his way for the rest of the game, though!"

Prostalgic 

a sentimental longing or wistful affection for the future, typically for a vision of what is likely to happen, typically accompanied with happy personal associations.

As I helped my father learn to use his new phone, I was overcome with prostalgia as I envisioned an older version of myself needing a similar level of care to master the holodeck. These prostalgic feelings almost always catch me in moments with my parents, especially now that I have a child of my own to track these passing years against.

Pornstalgia 

The state of nostalgic longing a person experiences when one encounters a pornographic movie or actress from one's past.

Like clockwork, pornstalgia sets in every time I watch Debbie Does Dallas.

pretalian 

Pretend Italian. The international and preferred language of Starbucks.

"I always get confused when I try to order coffee at Starbucks. I think it's because I don't speak pretalian."
