pull the plug on someone—
1. remove life-supporting equipment from a terminal patient:
- David’s prayers awoke his friend from a coma several days before they were going to pull the plug on him.
2. discontinue a person’s employment:
- Remember how many reporters complained and talked about Jayson long before his editors finally decided to pull the plug on him?
put a plug in for someone—highly recommend a person; promote smb.’s interests:
- Let me put a plug in for the new leader, the guy coming in to take my place. He is my longtime friend.
