Anzac Day is a national holiday in Australia and New Zealand, where men celebrate the the skin of their scrotum, affectionately referred to as the “anzac”, which is an aborginal term that means “i think these berries are dried out”.
We here in America tend to use the term ”ball sac” (see how it feels fancier without the “k”?), or coin purse (my personal favorite).
Kevin, my friend in New Zealand, would you care to elaborate in the comments section?

I think coin purse was meant to refer to what is known as the
“taint”, the area of skin between the Ball Sac and the anus… but maybe that is juat a Canadianism
