The term bluejacking was allegedly coined by a user of esato.com calling himself ‘ajack’, who sent various contributions to the site’s message board telling of how he had ‘discovered’ this one day when trying to deflect his boredom as he stood in a queue at the bank. The craze has popularised a derived noun bluejacker and a verb bluejack, which is often used in passive form, e.g. Are you being bluejacked?.
