The Fastest Thing Possible meme originated from scientific infographics comparing the speeds of various phenomena like sound and light. The template usually features a horizontal bar graph where the speed of light is dwarfed by a third, custom category representing an incredibly quick reaction or event. While the phrase is often associated with Sonic the Hedgehog's 'fastest thing alive' tagline, the visual meme format is widely used to joke about how fast people respond to specific triggers, such as a crush's text, a Steam sale, or the sound of a snack bag opening. It remains a staple for expressing relatable, hyper-fast human behavior through data visualization satire.
