Thunderstruck is a song by Australian rock band AC/DC, released in 1990 as the lead single from the album The Razors Edge. Built around a relentless guitar riff played by Angus Young, it became one of the band's most recognisable tracks and a staple at sports arenas and rock radio. Online, the opening riff and shouted title line were clipped into a short meme sound for entrances and reveals, where the lyric you've been thunderstruck works as a punchline for anything meant to feel powerful or shocking.
