Entertainment Sports Michael Phelps' Post-Race Finger-Wag Is Giving Twitter #Goals After Phelps took gold on Tuesday in the 200-meter butterfly, he threw his pointer finger in the air By Rose Minutaglio Published on August 9, 2016 11:25 PM Share Tweet Pin Email Photo: Ian MacNicol/Getty Images When Phelps took gold on Tuesday in the 200-meter butterfly (by 4/100ths of a second!) he celebrated his victory with a gesture that has become very familiar at the 2016 Rio Games – the finger wag. U.S. swimmer Lilly King first demonstrated the move following the women’s 100-meter breaststroke semifinals on Sunday. The athlete finger-wagged Russian competitor Yulia Efimova – who failed a doping test earlier this year – after Efimova finished first in her heat. “You’re shaking your finger number one and you’ve been caught for drug cheating. I’m just not a fan,” King told NBC at the time. On Tuesday, Phelps followed suit after winning his 20th gold medal. When the 31-year-old raised his pointer finger to the air, waving it back and forth, the crowd (including fiancée Nicole Johnson and son Boomer) responded with a resounding “Oooh!” For more of PEOPLE’s Olympic coverage, pick up our collector’s edition, The Best of the Games, on sale now.
