After winning the World Cup this year, a video of Rapinoe holding a bottle of Veuve Clicquot La Grande Dame in one hand with her trophy in the other blew up. During the clip, she turns to the camera and shouts: "I deserve this." It was truly iconic.
To capture this moment, you can carry a bottle of the famed champagne around with you to Halloween parties (you'll certainly be a hit with your friends if you share).
Alternatively, you can just get a cheaper bottle of champagne. Or just carry around a plastic champagne glass if you're worried about breaking a bottle or don't drink.
