squawk about (someone or something)
1. To talk about something in a loud, grating, obnoxious manner. He's spent the last half an hour squawking about the new girl he's dating. A: "What's Mary squawking about now?" B: "Oh, she's off on some long-winded explanation of postmodernism."
2. To complain about something in a loud, grating, peevish manner. If I have to listen to him squawk about the election for the next hour, I'm going to scream.
