The 'What The Hell Happened Here' meme features a scene from the 2019 Marvel blockbuster Avengers: Endgame, starring Paul Rudd as Scott Lang (Ant-Man). Upon returning from the Quantum Realm five years after Thanos' snap, Scott finds a world that is overgrown, desolate, and completely unrecognizable. The meme gained massive traction on platforms like Reddit and Twitter as a perfect reaction image for encountering a deleted comment thread, a bizarre public scene, or a sudden escalation in an online argument. It perfectly encapsulates the feeling of total bewilderment when stepping into a situation that has clearly gone off the rails during your absence.
