Nostalging 

The verb for the word "Nostalgia", which is the feeling you get when romantically yearning for the past, often in idealized form.

Nostalging is most common when stumbling upon a song you haven't heard since your younger days.

Lynch: Dude, I was nostalging so hard last night.

Fisher: Really, what happened?

Lynch: Remember the song "The Middle" by "Jimmy Eat World"? It was playing in the store last night!

Fisher: I haven't heard that song foreve--Ah man, now I'm nostalging! Ahh, those were good days...

Nostalgiatard 

Grown adults who are stuck in past and think that decades like the 90s were flawless. They're founded everywhere on social media and they hate certain things and technologies just because it wasn't from the decade they grew up with, but if someone likes those things then the nostalgiatard will force-feed you dumb excuses and call you names. They appear in all kinds of medias such as music, cartoons, movies, books, etc. Most of them usually spam these "only 90s kids know this" posts on social media sites. They have a large habit of comparing old media to new media. The "90s kids" who constantly brag weren't even from the 90s and were born in like 1999 trying to look cool. They always say that the 00s+ kids had a bad childhood even though every decade had its flaws and often stereotype the younger generations. They're founded in lots of YouTube comment sections, especially music videos. Most young kids are also nostalgiatards who weren't even around in decades like the 50s or 80s. They really love to hate on games like fortnite, cartoons like teen titans go, and music artists like justin beiber and make hate art and send death threats to the people who like those medias.

Person 1: I like TTG and S4+ SBSP!
Person 2: Dude those shows suck and you have bad taste!
Person 1: Ok nostalgiatard!

Nostalgiafag 

Someone who devotes their entire personality to "retro" and "80s - 90s" content. This can include music like vaporwave and shitty wannabe japanese 90s Tokyo drift bullshit with the lined background with compressed images. The only actual song from 80s era they could mention would probably be Africa by Toto. They will also show their nostalgifaggyness by wearing shirts with retrowave bullshit or by making it a wallpaper on their iphone200XLR.

"Hey my fellow hip-hoppy bro dude hear that tight vinyl resanance by my fellow broheims at HOME?"
"No you fucking NOSTALGIAFAG"
