What is hfy?

"HFY" is often used as an acronym for "Humanity, F*** Yeah!" and is associated with a genre of science fiction stories and art that celebrate the resilience and resourcefulness of humanity in the face of adversity. These stories typically involve humans triumphing against overwhelming odds, often in the context of conflicts with alien races or in post-apocalyptic scenarios. The term and its associated subreddit (/r/HFY) were coined in 2012 and have since spawned a large community of fans and creators.
