Nostalgurbate 

The act of nostalgurbation. To masturbate with the aid of forgotten favorite porn and/or fantasies from ones youth.

"I was cleaning out my old hard drive and found some old vids of Jenna Jameson. It brought back so many fond memories I couldn't help but sit down and nostalgurbate to those oldies."

Nostalgurbate 

Relive a childhood interest as a 30+ year old, usually resulting in feelings of shame and regret.

I'm going to nostalgurbate so hard to He-Man cartoons tonight.

Nostalgibate 

To engage in an activity that is nostalgic to you and experience Nostalgigasms

I had to Nostalgibate the other day, so I played some Crash Bandicoot and I got a huuge Nostalgiboner

I listened to some Beatles and felt the best Nostalgigasm in the world!
