Shock jocks

From OAPedia.com

Shock jocks is the collective term used by the media to describe any radio show hosts that are known for controversial and envelope-pushing material. The term has been applied to Opie and Anthony, Howard Stern, and Don Imus. O&A constantly object to being called shock jocks, as they feel there is more to them and their show than just shocking material, but unfortunately they're stuck with that label.
