Shuzo Matsuoka, a former professional tennis player, transformed into a massive internet phenomenon through his incredibly intense motivational videos. The meme primarily stems from a 2008 clip where Shuzo stands in freezing water, shouting 'Never give up!' (Akiramenna!) at the viewer to encourage them to persevere through challenges. His over-the-top passion and high-energy delivery led to thousands of 'MAD' remix videos on Nico Nico Douga, often pairing his shouting with anime themes or pop songs. Known as the 'hottest man in Japan' because his spirit is said to physically raise the local temperature, Shuzo memes are used to provide aggressive encouragement or hilarious parodies of hyper-positivity.
