Definition & Bedeutung von "flip side"

What is the origin of the idiom "flip side" and when to use it?

The idiom "flip side" originates from the era of vinyl records, which typically had two sides: an "A" side and a "B" side. The "A" side usually featured the main songs or singles, while the "B" side contained additional tracks. When you flipped the record over to the other side, you encountered different content. This physical act of flipping the record to reveal another side led to the metaphorical use of "flip side" to refer to an alternative perspective, aspect, or version of something.
