Take the number five, add the international distress signal and you've got a chart-topping band.
But what may surprise you is this band's music managed to help save a teenage girl's life.
Savannah began listening to the band's music two-and-a-half years ago. Their songs are mostly upbeat and fun which was the opposite of how she was feeling at the time.
She was being bullied and isolated by the kids at her school because of her appearance, being overweight and gaining good grades.
Savannah then turned to the internet and found solace in 5SOS's music.
She was devastated to learn they would not be coming to New Zealand despite efforts to organise a fan party as part of the Ignite Music mentoring programme.
But Story had a surprise for Savannah.
