"Radio Rapists" defines the people in the Radio Industry who choose the music for a particular Radio Station, and they usually "Rape" a song over and over until it is no longer appealing to the listener (If the listener found it appealing previously, which they usally didn't in the first place) or when it is no longer popular and another song takes its place.
Radio Rapists are VERY common.

Person 2: "Yeah man, it's all thanks to those damn Radio Rapists."
