The 'Bonus Meme' became an internet sensation through PewDiePie’s 'Meme Review' series on YouTube, where it represented the highly anticipated extra segment at the end of a video. What started as a simple addition turned into a massive running joke within the community, with fans frequently spamming 'Bonus Meme' in comments and creating petitions to ensure its inclusion. The concept typically involves the host clapping twice to signal the final reveal, capturing the thrill of unexpected or high-quality extra content. Today, the term is widely used across social media to describe an additional, often superior, joke or insight added to a discussion.
