>As for English, several years ago, the UK tried to outlaw any job description that indicated gender. For example, postman became Postperson. They had to backtrack on the law when someone pointed out that the Queen would become the Throneperson.

Once Charles ascends to the throne, they would not have that problem. I think "jackass" is gender-neutral. :)
