Question: Which two activites are closely associated with a popular 2004 concept which spurred  the hoax claim, Toothing?
Related documents: [0]  [DOC] Dogging is a British English slang term for engaging in sexual acts in a public or semi-public place or watching others doing so. There may be more than two participants; both group sex and gang banging can be included. As observation is encouraged, voyeurism and exhibitionism are closely associated with dogging. The two sets of people involved often meet either randomly or (increasingly) arrange to meet up beforehand over the Internet. [END] 
[1]  [DOC] Toothing was originally a hoax claim that Bluetooth-enabled mobile phones or PDAs were being used to arrange random sexual encounters, perpetrated as a prank on the media who reported it. The hoax was created by Ste Curran, then Editor at Large at the gaming magazine "Edge", and ex-journalist Simon Byron. They based it on the two concepts dogging and bluejacking that were popular at the time. The creators started a forum in March 2004 where they wrote fake news articles about toothing with other members and then sent them off to well-known Internet-based news services. The point of the hoax was to "highlight how journalists are happy to believe something is true without necessarily checking the facts". Dozens of news organizations, including BBC News, Wired News, and "The Independent" thought the toothing story was real and printed it. On April 4, 2005, Curran and Byron admitted that the whole thing was a hoax. There have, however, been real Bluetooth dating devices to hit the market since. [END]
