If you could provide more context, I might be able to help you figure out what the person meant.
For example:
* Did you see the word in a specific context? Was it in a conversation, a book, or online?
* Could it be a typo for a similar word? Perhaps "slothing" (referring to sloths), "smoothing," or "sloughing."
Let me know more details, and I'll do my best to assist you. 😊
