Ariarne Titmus, a twenty-year-old Australian swimmer, won gold in Monday's women's 400-metre freestyle final. She beat Katie Ledecky, the American champion.Titmus, who goes by the nickname "Arnie", beat Ledecky's personal record of 3:56.69. Ledecky put up a good fight with the last lap an exciting neck-and-neck push towards wall.Titmus' amazing win gave viewers and the Internet another unforgettable moment: Dean Boxall, her coach, getting absolutely wild with GIFable joy in the stands.Absolutely no hooting or hollering.NBC's commentary team noticed a resemblance to Doc Brown from Back to the Future.This instant of joy and vindication will be remembered for many years. It captures the essence of many famous sports GIFs, including Vince McMahon sitting back (yes, WWE counts), Rob Ryan fist pumping, and the Buckle Up Baby hockey child. All of these things are in one. Boxall, fueled only by adrenaline and pride, is clearly eager to tear down the stadium with his naked hands.We don't recommend that you rip your mask off in the middle of a pandemic or violently air-humping obstacles. Or terrifying poor facility staffers who weren't warned about how Australian men react when they win at sport. However, we can all recognize and relate to moments of hard-fought victory.This moment was captured and documented by the camera operators. Boxall should shout that the poor usher gets a drink after he is out of Ultimate Warrior mode.
