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!

Nostalgiatard 

An idiot who believes that anything from when he was 12 years old was better than now.

Person #1: "So, what are your favorite movies?"

Person #2: "Anything from when I was 12 years old, because they are so much better than today's movies!"

Person #2: "man, you are such a nostalgiatard!"

Nostalgiabation 

Occupying too much of your time with nostalgia.

I was supposed to meet up with Tim in town, but I got caught up in nostalgiabation by watching old cartoons from my childhood. He waited in town for four hours, until he was kidnapped by a homeless man.

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!

Cartoon Nostalgiatard 

Someone who only like the 90s and early 2000s cartoons and hates every cartoon afterwards. Their mostly millennials living in their mother's basement watching cable tv on their mother's old cube tv spending their lives ranting about cartoons like modern spongebob, TTG, on sites like YouTube oftenly saying that those who likes the cartoons they dislike have bad taste. Not to mention that they watch kid cartoons and rant about them but if you mention that they'll use the statement "animation isn't just for kids" it's true that animation could also be for adults but that doesn't mean you don't still look stupid when you rant about kid shows directly aimed for kids up to the age of 10 in your 30s. Lots of them are also enterbots and don't have their own opinions and blindly hate modern cartoons because other enterbots hate it.

Person: I like Kamp Koral and TTG...
Cartoon Nostalgiatard: Dude those shows suck and you have bad humor, at least we had good cartoons in my day!
Person: OMG here we go again...

To have a conversation with someone about the "good old days".
