The 'Select All Squares' meme is based on the ubiquitous Google reCAPTCHA 'I'm not a robot' verification system. It typically features a grid of images where users are asked to identify specific objects, such as traffic lights or crosswalks. The meme version subverts this by asking users to find abstract or non-existent concepts like 'true love' or 'a stable sleep schedule' within the squares. It gained massive popularity as a way to express frustration or cynicism toward modern life, often leaving the viewer to realize there are 'none' to click, just like the actual frustrating security checks.
