NBA Celebrations

What is it with NBA players celebrating nowadays? Whatever happened to the high five? The jumping up in the air and pumping your fist? Heck, I'd even take a butt slap or a group hug over what is going on now.
Maybe NBA players have had sensitivity training or were required to watch Brokeback Mountain. Lately celebrating a big win has included all too intimate hugs, or even worse, whatever Lebron James is doing there to his teammate. Is this the new face of the NBA? If so, at least they wear long shorts now.
