I'm not sure where Iggy Azalea came from, or why we as a society decided she should be famous, but part of her current tour includes a segment where a woman comes on stage to allow Iggy to get a nice whiff of her ass. Or something, who knows?
This picture comes to us courtesy of Drunken Stepfather (link below), and they give no context for it, forcing me to make one up. The way I see it, one of two things is happening here. Either this woman's ass has great acoustics, which is why she appears to be serenading her cornhole, or she's just incorporated her love of sniffing ass into her show.
I'm going with option B. It's much more plausible. I mean, how could this woman possibly have an ass that's equipped to broadcast music to a festival crowd? I think what we're seeing here is a woman that knows how important a nice whiff of ass is to a good performance. You gotta get your fill of ass before singing or rapping or whatever it is that this woman does. I couldn't possibly be bothered to look it up.
