It is a common expression in Hindi, conveying the sentiment of:
* Eternal love and commitment: It implies a promise to stay together forever, never parting ways.
* Unconditional love and devotion: It suggests a deep connection that transcends temporary separation or challenges.
* A longing for a lasting bond: It reflects a desire for a relationship that endures time and circumstances.
In a romantic context, it can express the hope for a lifelong relationship. It can also be used in a broader sense, to express a strong connection with friends, family, or even a place.
The phrase became popular in India after the release of a Bollywood movie titled "Kabhi Alvida Naa Kehna" (2006), which explored the theme of infidelity and the complexities of love.
