let the genie out of the bottle

The phrase "let the genie out of the bottle" is an idiom that means to allow a situation or problem to be released or made known, often resulting in unintended or uncontrollable consequences. It is derived from the concept of a genie trapped inside a bottle or lamp, who grants wishes when released but can also cause trouble if not properly handled or controlled. Thus, "letting the genie out of the bottle" suggests unleashing something powerful, potentially unpredictable, or difficult to put back in its place.
