This is McKayla Maroney.
You remember her from the perfect vault she did in the Women's Team Gymnastics final.
The one that was so good it made the judge's jaw drop.
Well yesterday was the Women's Vault Final, and Maroney was the hands down favorite to win gold.
Her first vault was unsurprisingly awesome.
But on the second vault the unthinkable happened.
Maroney fell down. According to Deadspin Maroney hadn't missed on a vault in her last 33 attempts. Even with the fall, she ended up missing out on gold by only .108 points.
Maroney's reaction to winning silver? Let out your inner "mean girl."
