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.

A sentimental longing for the pornography of the past.

Pornostalgia evidenced when watching porn: (i) "Where's the plumber/pizza delivery boy?"; (ii) "Where are the pubes?"; (iii) "Those ain't real"; (iv) "The production values of this movie really are first class"; (v) "Do you remember AIDS?".

Prostalgia 

(N.) The renaissance of culture and technology of the late 19th - mid 20th century, followed by "Prostalgia" or "Prostalgics". This culture movement is infused with modern day accommodations, and is based in the Baltimore, MD/Washington DC area, (which are major Hipster hot spots) and this movement is the classier brother of the hipster movement.

How to spot a prostalgic person;
What music they like, what they wear, and they're overall appearance tend to be that of your grandmother/father when they were young. These people tend to be confused with Hipsters, however, prostalgic people tend to uphold old values and ways of life, only using modern luxuries when strictly necessary. Prostalgic people also are connoisseurs of class, whereas hipsters have modern lifestyles infused with only a small bit of old world items.

Pure breakdown of prostalgic people to average people;

Avg. Person - 90% modern, 10% vintage
Hipsters - 80% modern, 15% vintage, 5% Starbucks
Prostalgics - +70% vintage, 30% modern

Here is an example of a Prostalgic being recognized at a cafe;

"Hey, is that a hipster over there at that cafe?" She asked.
"No, he's just prostalgia." He said.
"How do you know?"
"He's using a typewriter instead of a computer, see."

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.
