kiss off
Rude brush-off gesture
Kiss off is a dismissive rejection—telling someone to go away or that you're done with them: He asked for a raise and got kissed off.
As a noun, a kiss-off is the act of being dismissed or the brush-off itself: The letter was a polite kiss-off.
The phrase carries contempt, suggesting the person isn't worth further engagement.
