Im glad you like it bud!
Its actually a play on an avatar that has been making the rounds of the 'net for years.
As I get it, it is actually an anonymous, chunky young GIRL from somewhere in Russia, just going spastic - were talking giddy and jumping in glee. No one really knows why, or even who she is/was, except that, yes... she's real. As it has grown, people paste all sorts of things over her face now, from Bono to the Darth Vader image you see.
I even have one, a quartet of her with instruments - as a band! It's one of those weird urban legend things that just seem to tickle our collective fancy.
