The five piece dance troupe made up of Corey 18, Mike 18, Dylan 18, Jaih 17 and Mikey 19 took to the stage at the weekend.
When they revealed that they're called Boyband, Simon Cowell reacted: "That's not your name?!"
And when the group explained that they weren't even a band, the music mogul complained: "Is this serious? Honestly?"
While their name didn't win over Simon, Boyband went on to impress him with their dance moves.
He told the guys after their audition: "I've sat in this chair for a long time and I think with you we're seeing the future, I think what you've done together yourselves is exceptional and I've got the best feeling going forward."
Chatting to us this week, the boys - who won Ant and Dec's golden buzzer - insisted they weren't going to change their name.
They explained: "We actually didn't come up with it, it was given to us by one of our mentors, as we look like a boyband and it's just stuck with us through our characteristics and how we act as a groups."
Boyband declared: "We're going to stick with it."
With their golden buzzer, Boyband are through to the semi-final live shows and have something big planned.
