The 'Toilet Dark Souls Levels' meme (also known as Bathroom Boss Bar) is a visual joke that overlays the iconic health bar and UI elements from the Dark Souls series or Elden Ring onto photographs of bizarre, unsanitary, or 'cursed' bathrooms. It plays on the concept of 'environmental storytelling' found in FromSoftware games, suggesting that entering a particularly sketchy restroom is equivalent to initiating a high-stakes boss fight. The trend gained traction on platforms like Reddit and Twitter, where users shared photos of toilets in precarious locations—such as on a pedestal or in a dungeon-like basement—labeling them with epic, menacing names like 'The Porcelain Throne' or 'Vomitus, the Unyielding.' It perfectly captures the shared human experience of encountering a bathroom so intimidating it feels like a final boss battle.
