South africa out to be crowned double rugby world cup champions

I think there may be a small issue here!

South Africa has indeed won the Rugby World Cup twice, but not as "double Rugby World Cup champions". The Rugby World Cup is a single tournament held every four years, where national teams compete to be crowned the world champion.

South Africa won the Rugby World Cup in 1995, defeating New Zealand 15-12 in the final, and again in 2019, defeating England 32-12 in the final.

So, while South Africa has won the Rugby World Cup twice, they are not "double Rugby World Cup champions" as that would imply winning the tournament twice in a row, which has not happened.
