Californication is a made-up word that is used to describe the cultural phenomenon of California and its influence on popular culture. It combines the words "California" and "fornication" (which means to have sex), but it doesn't mean that people in California are always having sex.
The word "californication" is often used to describe the idea that California is seen as a place where anything goes and people can do whatever they want. It's also often used to describe the way that people from California are portrayed in movies and TV shows, as being laid-back, cool, funny, and sometimes a little wild.
While the word was originally invented as a way to describe the music of the band Red Hot Chili Peppers (they have an album called "Californication"), it has now taken on a wider meaning that goes beyond just California and music. It's an interesting word that captures something special about the culture of the Golden State and the way it is perceived by the rest of the world.
