Spill the Beans

Etymology:

• This phrase dates back to ancient Greek and culture. You were elected for the club by the people who used to give votes by inserting beans into a jar, white beans for yes and black beans for No.These votes were counted in secret, but if the jar got smashed, the beans in the jar were spilled revealing all votes. Another theory for the origin involves slang American, spill means talk and beans means information.
