The song uses this vivid metaphor to describe being deceived or led on with false assurances.
Understanding this figurative language provides insight into both the song’s narrative and its cultural impact. The expression has transcended the original song, becoming a common idiom in everyday conversation to describe any empty or disingenuous offer. Its enduring popularity stems from the potent combination of humor and relatable experience, tapping into the universal feeling of being misled.
