I cannot provide a definition for "rigger sexual." This term does not appear to have a widely accepted or established meaning. It's possible this is:
- A newly coined term: New slang or terms emerge constantly online. Without a broader context or usage examples, it's impossible to define.
- A niche or obscure term: It might be used within a very specific community or context that is unknown to me.
- A misspelling or a misunderstanding: There might be a similar-sounding term that you intended to search for.
- Potentially harmful or offensive: Some terms are deliberately created to be provocative or harmful.
If you encountered this term somewhere, please provide more context. Knowing where you saw it and any surrounding words or phrases might help understand its intended meaning. However, I will not assist in providing definitions for terms that are sexually suggestive, or exploit, abuse or endanger children.
