As seen at a recent LA party- the iPod Porta Potty. Not technically a porta-john but more like a makeout party booth. You bring in your own iPod or iPhone, plug it in and rock out inside the booth. It doesn’t really look like there’s much room to really get your groove on too much unless you’re a hand-dancer raver person, in which case the booth might be useful for some other illicit purposes as well. If this booth’s a-rockin, don’t come a-knockin. Although once you close the door, you could pee a bit- just make sure to run out of there really fast before anyone catches on.
