The Bottle Meme, often manifesting as the 'Message in a Bottle' or 'Bottle of Truth' format, revolves around the discovery of a hidden message that reveals a blunt or humorous reality. Functioning similarly to the 'Scroll of Truth' or 'Hard to Swallow Pills' templates, it provides a visual setup for a setup-and-punchline joke where the bottle contains an undeniable fact that the protagonist may or may not want to hear. The meme became a staple on platforms like Reddit and Tumblr because of its versatility in addressing everything from niche fandom takes to broad social commentary. Its enduring popularity lies in the relatable human experience of searching for answers, only to find something unexpectedly honest.
