A millennial who grew up in the mid to late 90s around the time the first DOOM game came out. They consider themselves their own separate group from the Millennial generation and they hold a deep resentment towards GenZ kids. They think the early 2000s were the best era of all time and every game made after that era will never live up to "the classics". Can usually be found wearing a dark clothes and a beanie in the back isle of the grocery store buying cigs or a 12 pack of Monster Ultra.
Doomer: *cracks open Monster Ultra* Look at that stupid Zoomer over there doing fortnite dances

Doomers

Millenial: I'm never going to do anything of value. I have to cry now, I can't handle this I'm just trying to get by
Gen Z kid: I'm never gonna do anything of value! lol

Millennial: Kids should be taught openly about mental health it’s very important! Gen Z:*rides in on Segway* What the hap is fuckening my gays *grabs some tide pods* lol what if I ate these.
Baby Boomer: Peace man!!!! Generation X: Long live Cobain!!!! Generation Y/Millenial: Who needs Peace and Grunge when you have Lady Gaga!!! Generation Z: I wish I could buy an iPad, but I'm in debt!

Used to describe someone who is overly obsessed with global problems.
You might have a doomer on your hands if:

1. He keeps talking about the end of the world
A doomer is obsessed with global problems and will not hesitate to drag you into a five-hour long lecture just to tell you more about his opinion towards global problems.
2. He urges you to take more public transport frequently.
A doomer is very worried about climate change and will do anything he can to stop it. This is of course, good until it reaches a point where he asks you about your car or something every day.
3. He frequently watches the news, and tells people about it.
Someone who is in love with global affairs will definitely not want to miss the news, so a doomer will definitely try his best to catch the news everyday, sometimes even asking you to join him.

Hope you understand what a doomer is now

In the gaming world, this individual constantly states that games nowadays are not as difficult, good, challenging, or as exciting as games were when they were a kid. They downplay modern video games and brag about the "good old days" of their youth.

DOOMer is a play on the word Boomer with a DOOM (popular video game for retrogamers) emphasis.
EX1:
Man, I'm really over watching XPLoot play CoD on stream, he's such a DOOMer.

EX:2
DOOMer: Video games used to be more difficult when I was a kid!!
Anyone Else: Okay, DOOMer!!

Someone who that revels in the thought of destruction of the planet or humanity due to global warming.

Antonym: denier.

Doomers hold an unshakable faith that the planet is inevitably doomed because of anthropogenic global warming and that nothing can reverse earth's ultimate destruction. In particular, doomers seem to take joy in discussing and contemplating a global doomsday.
The doomer took great joy in debunking a report that suggested that global warming doomsday predictions were exaggerated.
