Somebody That I Used to Know was released in 2011 by Australian artist Gotye, featuring New Zealand singer Kimbra, and became a worldwide number one built around a sample from Luiz Bonfá. Its stark video and singalong chorus kept it in pop culture long after the charts, and short clips resurfaced on TikTok and meme pages as a shorthand for estrangement. It now sits alongside Hello darkness my old friend as a go to lyric for mock heartbreak and distant exes.
