A reference to the American rock band Phish. Page McConnell, the band's pianist, is positioned stage right during live performances. Fans seated in the audience stage right are said to be "Page side" and the high energy and guaranteed fun of enjoying a Phish show from Page side gave way to the now common phrase "Page side-rage side," where "rage" is synonymous with "party."
"The mail order tickets I got are behind the stage, but I'm definitely moving to Page side-rage side by the second set."
