The 'Reese's Puffs Rap' meme originates from a 2009 television commercial for the cereal featuring a group of kids performing a catchy hip-hop track with the iconic lyrics 'Eat 'em up, eat 'em up, eat 'em up, eat 'em up!'. While always a nostalgic relic, the song gained massive viral status on TikTok and YouTube through complex audio mashups, most notably the 'Misery x CPR x Reese's Puffs' trend. In this context, the song represents chaotic, high-energy, or upbeat vibes that often clash humorously with more serious or melancholy themes. It is frequently used to highlight situations where someone is unexpectedly enthusiastic or to signify a sudden shift in tone during a conversation or video.
