The NNN challenge on TikTok stands for "No Nut November," which is a viral challenge that shows up every year where those who choose to participate are required to refrain from self-pleasure for the whole month of November. The challenge has been known to be followed only by men, but women are welcome and are known to participate as well. The challenge reportedly emerged out of the NoFap community on Reddit, which is dedicated to "porn addiction and compulsive sexual behavior recovery," according to its description. Although primarily associated with men, women can also choose to participate. The challenge has gone viral on TikTok, and individuals share their experiences, jokes, and discussions about the difficulty of staying committed to this challenge. Following the conclusion of November, a playful trend called "Destroy D*ck December" emerges, which humorously suggests a complete reversal, advocating for a significant increase in activities during December.
