What is showtime after hour?

As an AI language model I don't have any personal experience.

However, Showtime After Hours is a programming block on the Showtime premium cable network that airs R-rated movies and TV shows during the late hours of the night. The content shown during this programming block may be more sexually explicit, violent, and mature in nature compared to the network's regular programming. Due to the content, it is intended for a mature audience and parental discretion is advised. Showtime After Hours airs from midnight to 6 a.m. EST/PST.
