A prostitute who rather than selling sex and things like that, sells hugs.
Depending on how good the hug prostitute is at providing their service, you may have to pay rather a lot for a good hugging session.
Some hug prostitutes run special offers where they come up to you in the street and ask if you'd like a one-off free hug.
One of the only forms of legal prostitution is hug prostitution.
If you don't pay a hug prostitute after you are satisfied hug-wise, they attack you.
Hug prostitute: I'll spoon you for the night but it'll cost you £100.
