Ep 9. #REHASH

In South Park season 18 episode 9 titled '#REHASH', the residents of the Colorado town are thrown into a frenzy when a new social media app takes over. The app, called "Sh*tter," becomes wildly popular as everyone begins to obsess over documenting every moment of their lives and receiving likes and followers.

The boys, of course, are not immune to the trend, and they soon find themselves trying to outdo each other in their social media presence. Meanwhile, Randy becomes obsessed with creating viral videos for his farm business and even enlists the help of Butters to make a video promoting his farm's latest product.

As the episode progresses, the negative consequences of the app's popularity begin to emerge. The constant need for attention and validation leads to isolation and loneliness, and the desperate attempts to create viral content lead to dangerous stunts and injuries.

The episode also addresses the issue of "rehashing" content, as the residents of South Park begin to recycle old jokes and memes to try to stay relevant on the app. This eventually leads to a hilarious and chaotic climax, as the people of the town come together to create a massive, over-the-top "rehash" of all their old content.

Overall, '#REHASH' is a scathing commentary on the dangers of social media obsession and the pressure to constantly create new and exciting content. With its trademark humor and biting satire, South Park once again manages to entertain, shock, and make its viewers think all at once.
