Originating from fan art and high-quality 3D renders of the Dragon Ball character Broly, the 'Broly Boost' (often associated with the Broly Culo trend) became a staple of internet shitposting and anime communities. It features Broly in a dramatic, exaggerated pose that emphasizes his massive physique and 'legendary' power. The meme is typically used to represent a sudden surge in confidence, a massive upgrade, or simply to catch viewers off guard with its absurdly muscular aesthetic. It follows the lineage of the Omni-Man 'thicc' memes, blending high-stakes anime energy with ironic humor.
