The 'Iceberg' meme format originates from a popular stock photo showing an iceberg split by the ocean's surface. In meme culture, it is used to represent the 'tip of the iceberg' concept—where surface-level knowledge represents mainstream or well-known facts, while the massive submerged portion symbolizes increasingly obscure, deep, or bizarre trivia about a specific topic, community, or franchise. Users typically add tiered text layers descending into the ocean to map out levels of depth in lore, conspiracies, or esoteric information.
