proclaim something from the housetops
proclaim (something) from the housetops
To share some news or information publicly and with as many people as possible. I was ready to proclaim from the housetops that we'd be having a baby, but my wife wanted to wait for a while before we made the news public. I know you want to proclaim it from the housetops that you came in first in your class, but you should think about how it might make the other students feel and have a bit of modesty about it.
