No music of Mariah Carie's during the month of November. This will protect people from hearing her "All I Want For Christmas" song on the first two days of November, at least. Along with NNN (No Nut November), the goal is to win by not playing the song.
Person 1: "All I want for Christmas- iiisss.... youuuuuu~"
You: "Oh. You lost NMN"
Person 2: "What is that??"
You: "No Mariah November."
