The PewDiePie meme library is vast, but the most iconic template features Felix Kjellberg in front of a presentation screen, known as the 'And That’s A Fact' meme. Originating from his 'LWIAY' series on YouTube, this template is primarily used to present personal opinions or objective truths in a humorous, authoritative way. It captures Felix's signature blend of comedy and blunt delivery, allowing fans to highlight common sense or call out internet trends. Over the years, PewDiePie's expressions have become foundational to YouTube culture, representing everything from 'floor gang' pride to the evolution of modern meme commentary.
