Zoinks has been Shaggy Rogers's signature exclamation since Scooby-Doo, Where Are You! first aired in 1969. The nervous, elongated word became shorthand for the character's cowardly panic whenever the gang stumbled into a haunted house or a monster in disguise. Decades of reruns, films, and online clips kept the line familiar to new generations, and short soundboard versions spread through reaction videos, gaming streams, and memes. It endures because one word instantly signals cartoon fear, nostalgia, and comedy without needing any setup.
