Khela Hobe, meaning game on in Bengali, became a defining slogan of the 2021 West Bengal assembly election campaign in India, where it was used by the Trinamool Congress and its leader Mamata Banerjee at rallies and in campaign material. The phrase spread quickly on social media, where supporters turned it into songs, chants and short videos, and it soon moved beyond politics into cricket, football and everyday rivalry. It remains popular because its short, combative energy works as a universal call to compete.
