Jalkejai
From Tardis Wiki, the free Doctor Who reference
Jalkejai was a planet known by Bernice Summerfield. During an exploration attempt, there was a faulty mistranslation, almost leading to a war with between the natives and the explorers. Luckily, the natives resolved all conflicts with group sex.
It was later suggested that the dictionary had been tampered with on purpose. (BNA: Walking to Babylon)
