It's possible that:
* It's a misspelling: Perhaps you meant "wine" or "weenie."
* It's a slang term: It might be a local or informal slang term with a specific meaning.
* It's a made-up word: It could be a fictional term or a personal invention.
To help me understand, can you provide more context about where you encountered this word? For example:
* Where did you see it? (e.g., online, in a book, in conversation)
* What was the surrounding text or conversation?
With more information, I might be able to figure out what "weinis" means.
