pull the plug

The phrase "pull the plug" refers to the act of stopping or ending something, often abruptly or prematurely. It is derived from the literal act of disconnecting an electrical plug to cut off power supply, which metaphorically signifies putting an end to an activity, project, or situation. It can be used in various contexts, such as terminating a project, discontinuing financial support, withdrawing life support from a seriously ill person, or simply stopping or canceling any ongoing action.
