grand gesture

An especially elaborate, showy action, typically to win someone's love. I don't need grand gestures from my boyfriend. He shows me he loves me every day in a million tiny ways. A: "Do you think I could win her back with some sort of grand gesture?" B: "What, like surprising her with a choreographed dance routine or something?" Back in my day, you just called someone and asked them to the prom. Why do kids make such grand gestures?
