This reminds me of a story...
So I have some weird friends. One day (just after the Miley Cyrus VMA bonanza) my friend came up behind me and put her butt to the side of my head and started shaking. So I turn and I'm like "wtf are you having a butt seizure?" And she's like "it's called twerking!" Not knowing the evil I had wrought, I asked "what's that?"
About 1 hour of dance lessons later, and I could finally twerk like Miley. The end.
For some girls it's their sole dream to be a stripper and they want all other girls to feel the joy of stripping for horny men so they invented twerking. Next up we examine the occasional "pants on the ground" kid that envies prison inmates being butt-plugged.
Unfortunately I've seen or heard of 5yr old girls twerking because their older sister does it. It kind of kills me on the inside. And I HAVE seen the Miley Cyrus twerking video. I have lost all faith in humanity.
