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
