The line comes from 'I Write Sins Not Tragedies', the 2005 breakout single by Panic At The Disco from their debut album A Fever You Can't Sweat Out. The song's circus-themed music video, which won Video of the Year at the 2006 MTV Video Music Awards, made the band a defining act of the mid-2000s emo pop wave. The toast lyric lived on as a standalone soundboard staple because it works as a universal celebration cue, showing up in victory edits, wedding parodies and sarcastic toast memes across short-form video platforms.
