Someone who lives vicariously through listening to police and/or fire scanners. Generally someone who has an uninteresting life of their own, or flat out nothing
better to do. Some say it's a disease caused by people who only wish they could be a Firefighter, EMT, Paramedic, Sheriff's Deputy or Police Officer...we may never know! A few scanner hounds have taken to the extreme and created
Facebook pages/Twitter Feeds to inform the public each time
something happens on the scanner. Another extreme, scanner hounds that turn into Ambulance Chasers, so they can get a first hand glance at the 'action'.
If someone you know is suffering from being a Scanner Hound, simply
slap them in the face and tell them to get a life!
That
guy is a hard core scanner
hound, he walks around with his scanner on, his
phone, and iPad listening to 3 different stations at once!
