Cigarette after Sex is the name of an American band. A friend of mine showed me the song by them, "Apocalypse", and it's still one of my favorite songs. Quite melancholic, but so melodic and just special. According to the band's singer and founder Greg Gonzalez, the name of the band came to life: "A lot of our songs are autobiographical and the name is no exception. I had a "friendship with certain benefits" with the one girl who always smoked after we got together. I had never really tried it until she showed me. One night when we were together and smoking, the name popped into my head. It was literally what we just did."
