What is refrain in a 1965 hit by the who?

The refrain in the 1965 hit "My Generation" by The Who is considered one of the most iconic and memorable elements of the song. The repetitive and defiant chorus, "Hope I die before I get old," became a rallying cry for the rebellious youth of the 1960s and encapsulated the spirit of the era. The refrain is sung with raw emotion and attitude by lead vocalist Roger Daltrey, further emphasizing the song's message of youth rebellion and defiance against the older generations. The powerful impact of the refrain helped solidify "My Generation" as an anthem for the emerging counterculture movement of the 1960s.
