Jon Rahm chugged from his U.S. Open trophy and then punished a glow-in-the-dark golf ball to the moon ... and the awesome scene was all captured on video!!
The golf superstar -- who just took home the U.S. Open crown after an amazing four days at Torrey Pines last weekend -- hit up a restaurant patio somewhere in the world this week ... and then magic ensued.
Check out the video ... Rahm slurped down some sort of drink (odds are pretty solid it was an alcoholic beverage) and then he absolutely hit a missile off the floor!
