Usually involves Clear Channel Communications or Entercom. An automation system. Recordings of dudes with huge egos flirting with teenage girls. Reverb. Pitched up music. And the same cRAP played over and over and over and over and over and over and over again until you want to throw your radio out the window.

Can also mean other things. Depends on the city.

The afternoon presenter on kiss fm here in algarve portugal. Only got the show when Frankie Shanley left after being bullied by the breakfast presenter Simon frater. Coincidentally , spike hammond is Simons best friend and been doing a free show on kiss for 8 years. He got jealous over frankie. No one listens anymore to kiss over them and court is pending. Watch this space and ignore the nonsense they post on social media to distract from whats really going on.
