“Zoinks” is closely tied to Shaggy Rogers from the Scooby-Doo franchise, where it became one of his signature panic phrases across animated TV appearances and later adaptations. Online, the clip spread as a shorthand reaction for fear, confusion and exaggerated cartoon alarm. Its staying power comes from how short and instantly readable it is: even without context, viewers recognize the nervous Scooby-Doo energy and the joke lands in a fraction of a second.
