What the Hell Was Going on @ F15teen This Weekend?

<p>
  What the hell was going on at F15teen this weekend?  <a href="http://pictures.stldrunks.com/thumbnails.php?album=596&page=1">STLDrunks.com</a> has the photos above and plenty more, but I have no idea what the deal was.  At the surface, it seems like a regular bikini content, but some of these picture lead me to believe otherwise&#8230;

  Was anyone there?
