Jump down Someone`s throat !

(become angry with someone)

That's it, Greg! You'd better not come in after midnight again tonight.
I know, dad. You don't have to jump down my throat! I told you that I'd make it home around 11:50.I don't intend to be late!
Well, you've said that before and in you come at 2:50 in the morning. You can't blame me for getting angry and scolding you. I've got good reason.
