1. Cost
2. Why risk alienating a lot of your potential audience? I'm sure young female (and a lot of men) would not be thrilled to have a "broke dick" pedal.
The Broke Dick is something of a special case, I think. It was a limited run, inside joke due to a particularly unhappy customer here on TB.
That said, your general point stands. I couldn't bring myself to get something called a Big Muff or a swollen pickle. The Photon Death Ray is fantastic though.
