Here are some nuances of the term:
* Historically: It was often associated with a traveling lifestyle and a more nomadic existence.
* Modern usage: It can be used in a neutral way, simply describing someone who works in the carnival industry. However, it can also be used in a pejorative way, implying that the person is dishonest, untrustworthy, or involved in scams.
* Popular culture: In movies and TV shows, "carny" characters are often portrayed as eccentric, charming, and sometimes even shady.
It's important to be aware of the potential negative connotations of the word before using it. If you're not sure how someone might perceive it, it's best to use a more neutral term like "carnival worker" or "circus performer."
