When someone expects the worst possible scenario, regardless of there being evidence to support them. The poster will usually mention that they hope it doesn't happen. However, everything they say always reeks of pessimism.

doomposting 

Name used to refer the prominent facebook group (usually named La Pasión del Doomposting) that makes memes and posts related to Doomentio, a mexican anime reviewer, and his controversial statements and tweets.

I really like doomposting, it's funny how they make fun of all the nonsense Doomentio says.
