A more thorough explanation:

Open lewdness refers to gross, wanton, and public indecency that is outlawed by many state statutes. It is a sexual act that the actor knows will likely be observed by someone who will be affronted or alarmed by it. This term is also known as lewdness.

For example, if someone exposes themselves in a public place, they could be charged with open lewdness. Another example could be engaging in sexual activity in a public park where others can see.

These examples illustrate the definition of open lewdness because they involve sexual acts that are done in public and can be seen by others who may be offended or alarmed by them. It is important to note that open lewdness is illegal and can result in criminal charges.
