The line comes from the 2003 comedy Old School, where Frank Ricard, played by Will Ferrell, delivers it as an exuberant declaration of friendship. As short movie quotes became easy to clip and reuse, the line travelled beyond the film into reaction videos, sports edits and friendship montages, where its earnest, over-the-top tone made it easy to reuse out of context. It has stayed popular because it says loyalty in a single second, without needing the viewer to know the original scene.
