Out of curiosity, I have conducted an extensive research on the topic. Joking. Just merely googled the term yesterday and popped out that, apparently - as it has been already mentioned here in the thread by others - the month of november is to be followed by another interesting acronym, which, by the way, contrary to what one might think, has nothing to do with a cup size. It's called ddd, which stands for somenthing like destroy your d Dicember. It really makes the whole thing even less comprehensible.
What happens to the so-called superpowers you allegedly have gained in November? And what kind of superpowers they are even talking about? I read that the term took off after few posts on reddit, which I believe is also the same place where people take horse drugs medical advice from. So, I mean, it makes sense after all. You can't really make this stuff up.
