indelicate

adj

1. Improper or immodest.

   “As late as the 1950s and early 1960s, when "funk" and "funky" were used increasingly in the context of jazz music, the terms still were considered indelicate and inappropriate for use in polite company.”

2. Coarse or tasteless.
3. Tactless or undiplomatic.

   “Schuetz acknowledges that he knew about the Dale Barbre murder investigation as it was reported in GCN. Yet the Barbre murder saga provided only the skeleton — if I may be forgiven the indelicate word choice — for the story they concoct.”
