Petra Kvitova, Agnieszka Radwanska, Sloane Stephens, Simona Halep, Garbine Muguruza, Victoria Azarenka, Roberta Vinci, Carla Suarez Navarro, Sania Mirza and Martina Hingis are all featured in the clip, as are 22 popular emojis.

Most of their imitations are spot on, except for the upside-down smiley face. It's easily one of the most beloved new emojis, but it's got nothing on the taco, of course.

Last year the first WTA Emoji Challenge went down in Rome, and it ended up being the inspiration for @WTAreactions, which has since amassed over 23,000 followers.
