I think a lot of people mean "Wedding DJ" or "Radio DJ".

However there is a whole small subculture around this. A friend would go hunting for records to sample in Charity shops for old vinyls (this was pre-ebay). This apparently is known a "Digging" and lot of Music Producers, DJs etc would do this to find samples for their sets/albums.

Similar you have people using tracker software on old Amigas / Ataris to play sets.
