There is no widely documented public origin for this short greeting, and it appears online mainly as a user-shared soundboard clip rather than a line from a well-known film, show or song. Its appeal comes from its specificity: a hello addressed to one named person travels well as a joke, a dedication or a playful tag for anyone called Carolina, especially in Spanish-speaking chats and short-form videos. Because it is only about two seconds long, it is easy to drop into edits without disrupting the pacing, and that brevity has helped it keep circulating as a niche personal shout-out.
