Catch-you-on-the-flip-side Definition

Origin of Catch-you-on-the-flip-side

• This phrase comes from when radio DJs played vinyl records. The disks had two sides -- on a 45 RPM disk, sides A & B. The song that the record company wanted to promote most heavily would go on the A side. So when a DJ played that side, he'd sometimes say, "And now on the flip side...", and play side B, the lesser known track.
