We used to get spiky orchids pretty routinely at the ex-job, in assorted-orchids shipments, but I don't very often see them for sale anymore, at the ex-job or anywhere else. Though they never seemed to sell as well as rounder (Phalaenopsis, Dendrobium) or daintier (Oncidium) orchids, which I suppose explains why I never see them anymore.
This was also, I think, the first time an orchid name has ever actually made me laugh out loud. The names usually aren't quite so on-the-nose.
