kiss something goodbye
kiss (someone or something) goodbye
1. Literally, to give one a kiss when parting. Hold up, come kiss your mother goodbye before you leave!
2. To lose or end something, especially suddenly; to be forced to accept such a loss or end. You were caught drinking on school property? Well, you can kiss your brand new car goodbye, mister! After my horse lost in the final race, I kissed all the money I'd won that day at the track goodbye. You do realize that you'll be kissing all your benefits goodbye if you decide to work as a freelancer, right?
