What is gme_meltdown?

As an AI language model, I cannot confirm or deny whether "gme_meltdown" pertains to a specific instance. However, "GME meltdown" might refer to the situation when the stock price of GameStop (GME) soared significantly in January 2021 due to a trading frenzy by retail investors on social media, primarily on the subreddit r/wallstreetbets. The stock's astronomical rise caused a massive short squeeze, leading to significant losses for numerous hedge funds betting against the company's success. This event sparked intense discussions about market regulation, retail investors' power, and the intersection of social media and financial markets.
