To spill the beans literally means to tip out beans so they fall from a container. The image is concrete and physical, but the expression is rarely used this way in everyday speech. The literal picture helps make the idiom memorable.

In ordinary English, spill the beans means to reveal a secret or disclose information that was meant to stay private. It often suggests that the information comes out unexpectedly or before the right moment. The phrase usually carries a sense of informality and surprise.
