I didn't get it at first

I still don't get it

Don't get it either. ._.

WUT

I think it is either where r the moon moon posts, who is moon moon, or why so many moon moon posts

It's a trend that started on where..someone posted one of those "first letter of your name first letter of your last name" pictures and someone's new name turned out to be moon moon and that's were it started

lets bring back moon moon!!
