chafe at the bit
To be impatient and/or eager for something to happen or over some delay. Used to liken someone to an overexcited horse straining against its bit (the metal piece of the harness that fits between its jaws). The crowd chafed at the bit to see the unveiling of the new building. I've chafed at the bit for an opportunity like this my entire life!

Used to liken someone to an overexcited horse straining against its bit (the metal piece of the harness that fits between its jaws). I was chafing at the bit for the game to start. After two hours of waiting in the airport lobby, we were chafing at the bit to finally get on the plane.
chafe at (something)
To feel or express annoyance in response to something. Bruce chafed at the idea that the new hire he was training made more money than him. You could tell he was chafing at the reporter's questions, but he still declined to comment.
