Dyssiopeia

Dyssiopeia was the only planet where the inhabitants communicated with each other exclusively through insults.
The Twelfth Doctor had heard of the planet but never been. When he and Clara Oswald arrived, the Doctor quickly ingratiated himself with the locals and encouraged Clara to join in, only for her to say something so offensive that the two were chased out. (COMIC: Planet of the Rude)
