The Brady Bunch meme is derived from the iconic opening title sequence of the 1969-1974 television sitcom, which features the cast members in a distinctive 3x3 blue-bordered grid looking at one another. While the show itself is a cornerstone of TV history, the meme evolved to represent group dynamics, reunions, or comparisons between different people or objects within a shared space. It is most famously used to parody the 'Marcia, Marcia, Marcia' trope of sibling rivalry or to create 'alignment charts' for various fandoms. The grid format allows creators to humorously categorize characters or social groups, making it a versatile tool for commentary on jealousy or collective identity.
