A kissogram was a message delivered by a man or woman paid to do so, which involved the messenger flirting with and kissing the recipient. It described both the message and the person delivering it.
Before she started modelling, Amy Pond worked as a kissogram. For this job she wore a skimpy uniform for police officer, a french maid, a nurse or nun's outfit. (TV: The Eleventh Hour) Rory Williams apparently found the police uniform very sexy, since Amy wore it on their honeymoon. (TV: A Christmas Carol)
