It's possible that:
* It's a typo or misspelling: Perhaps you meant a different word, and there was an error in typing.
* It's a made-up word: Someone could have created it for a joke, a fictional story, or a specific purpose.
* It's a misheard word: Maybe you heard someone say a different word that sounded like "sclaptucasaptic".
If you provide more context, like where you encountered this word, I might be able to offer a more specific answer.
