My man did take it too far.
But as a dad, I'd be lying if I said I wouldn't be pissed enough to think of something (not actually do it) like this if I found out one of my girls had been twerking. That said, those air soft joints hurt and shooting people is never the move.
Bet she doesn't do it again though.
I would say that she was alright though, don't think it really hurt that badly since she was in the bathroom right after looking composed. "Twerking" really is a pretty disgusting dance, especially for little girls to take up and replicate. I'm with the brother on this. But American society is so explicit these days, what can you expect from kids growing up in this generation?
