Abracadabra is a long-established magic word, traditionally spoken by stage magicians at the moment a trick is completed, which is why it still signals a sudden transformation. Online, short spoken versions have become a handy shorthand for reveals, pranks and before-and-after edits, because listeners understand the reference without any explanation. Its appeal is partly nostalgic and partly practical: the word is instantly recognisable, easy to place over a cut, and playful rather than serious, so it suits comedy edits as well as light-hearted magic-themed content.
