It is a spirit in the month of November. It basically is a time when no man can not "bust a nut", such as ejaculating/masturbating. It also means that they cannot have sex with anyone, but they can kiss, as said by the news.
The challenge that throughout the entirety of November you aren't allowed to eat any form of nut, e.g. almonds. It is often tradition to feast entirely on nuts on December 1st for partakers, and victors, of this challenge.
"I'm really craving some nuts right now"
"But it's No Nut November, I know you can pull through until December. It will be worth it when you feast upon the December 1st nuts."
