The McKayla not impressed face or meme comes from gymnast McKayla Maroney. The infamous scowl she is wearing on her face came from a photograph taken at the 2012 Olympics in London. Many people thought she would win the gold medal for the competition but failed her vault and landed on her backside, receiving the silver medal.
While McKayla was standing on the podium she was caught making displeased facial expression and it went viral after it was released on Tumblr. Since then, there have been countless amounts of jokes and memes built around her 'not impressed' look. She even got President Obama to pose with her in the White House with the 'not impressed' face. McKayla's face is now photo shopped into every situation where disappointment lies.
