Hotel Transylvania introduced Dracula as a warm, overprotective father running a hotel for monsters, and his exaggerated bleh became a shorthand for the character's playful vampire identity. Clips of the line circulated online as a short reaction sound, shared in edits, memes and Halloween videos because it is instantly recognisable even without any picture. Its appeal has lasted because it works as both a character reference and a joke in its own right, turning a classic monster into something funny, friendly and easy to reuse in short-form content.
