It's possible that:
* It's a misspelling: It might be a typo of another word, or a mispronunciation of a word from a specific language.
* It's a regional slang term: It could be a slang expression used in a particular region or community, but not widely recognized.
* It's a fictional term: It might be a made-up word from a book, movie, or video game.
To help me understand your question better, please provide more context:
* Where did you encounter this word? (A book, website, conversation, etc.)
* Can you give me a sentence where you heard it used?
* What was the topic being discussed?
With more information, I might be able to help you figure out what "yowelo-to" actually means.
