Professional bowler Pete Weber delivered one of the most iconic and nonsensical lines in sports history after winning the 2012 PBA 68th U.S. Open. Following a high-pressure final strike, Weber turned to the crowd and shouted 'Who do you think you are? I am!' at a heckler who had been bothering him. While grammatically confusing, the raw emotion and sheer confidence of the statement turned it into an instant viral sensation. The meme is now used to represent moments of extreme self-assertion, over-the-top confidence, or when someone successfully shuts down their critics with a display of skill. It resonates with anyone who has ever felt like the 'main character' after a hard-earned victory.
