Podcast platforms like Apple Podcasts don't have a clear cut definition of what is considered explicit.

However if your podcast episode contains any words, topics or references to any content that may be considered age sensitive subjects, then we usually recommend you mark your episode as explicit. It doesn't impact your podcast at all, it just gives it a parental advisory label.

It is much better to mark an episode as explicit even for just one or two words rather than have the episode flagged as inappropriate by listeners and removed from podcast directories.
