Scrotum flap?!

So I opened my weekly email from ALA (the American Library Association). The first story has the headline, "Scrotum Flap Raises Ruckus Over Librarians' Sensibilities." Despite all of the bizarre spam email that I have received over the years, I believe that this is the first one that begins with the words, "scrotum flap." And then, "raises." And the email in question is from ALA.
