The 'This Does Put a Smile on My Face' meme originated from the teaser trailer for the 2018 blockbuster 'Avengers: Infinity War.' In the scene, the Mad Titan Thanos expresses his sadistic pleasure while pursuing the Infinity Stones, though the specific line was a voiceover that became synonymous with his character's dark resolve. Internet users quickly adopted the phrase to describe feelings of grim satisfaction, perverse joy, or simply the feeling of a plan coming together perfectly. Whether it's used for niche hobbyist victories or relatable daily wins, the meme captures that specific sense of inevitable and rewarding triumph.
