The 'Extra Thicc' meme originated from the animated series Samurai Jack during its long-awaited fifth season in 2017. In the scene, the villainous Aku is seen on a telephone ordering an assassin, where he famously describes a giant creature's proportions as 'Extra Thicc.' Voiced by Greg Baldwin, the delivery of the line instantly became a viral sensation due to its unexpected use of modern slang in a classic show. It quickly evolved into a popular reaction image used to express appreciation for something substantial or simply to mock over-the-top character designs. On the internet, it stands as a cornerstone of 'Thicc' culture and remains a staple for fans of the show and meme enthusiasts alike.
