It is what it is: a facial for your butt, a butt-acial if you will.  In fact several people you know might already have participated in this wondrously strange new way of wasting money at the spa.  Both Renee Zellweger and Ali Larter reportedly had their butts buffed-that seems redundant, but anyway, as we all know, once the celebs start doing it, it has got to be cool.  And who doesn’t want a freshened up bootee?  Personally, having someone meticulous go over every inch of my bottom side doesn’t seem appealing, but then what do I know?  Botox became a trend and that just sounds downright horrifying.
