There is a grandeur to the Oxford English Dictionary, especially when defining naughty words. Exempli gratia, the second edition, published in 1989, has this:
Prostitution: The offering of the body to indiscriminate lewdness for hire (esp. as a practice or institution); whoredom, harlotry.
The Inky Fool is dedicated to combating discrimination in all its forms, and is therefore wildly in favour of indiscriminate lewdness, especially as neither word seems particularly necessary to the definition.
