It’s been 20 years since Hanson came out with “MMMBop,” which, for some of us, means 20 years of singing the wrong lyrics.

The brothers cleared up a common lyrical mistake in a new interview with the Kyle and Jackie O Show. “Too many people put a ‘wop’ in there,” Zac Hanson, the youngest brother in the group, revealed. “What happens is people go to sing that song and they start making it up as if it’s nonsense. But it’s actually a repetitive part, it came from doo-wop songs. So it’s a background part.”

According to Google Play, the lyrics are as follows:

Mmmbop, ba duba dop / Ba du bop, ba duba dop / Ba du bop, ba duba dop / Ba du, yeah

Zac also talked about the real meaning behind the song. “‘MMMBop’ represents a frame of time; ‘in an MMMBop they’re gone,’ it says in the lyrics of the song,” he explained. “The whole song’s about the fact that almost everything in your life will come and go very quickly. You’ve got to figure out what matters and grab onto those things.”

This part is less shocking, as loyal Hanson fans have adopted the hit as their anthem.
