The complete reversal in the Brazilian male psyche I cannot explain - never to be seen now (except on the girls, and maybe the guys decided that it was time to make a distinction). Whatever the reason the sudden change appeared to have happened almost overnight.

The saleslady told me that most Brazilian men wear sungas smaller than the 6" side suit I got, but said the 6" version is popular for US.

They are definitely cut differently than typical briefs. In most US briefs, the back is cut larger than the front. But in these, they are similar. There's a picture of a blog that has some examples:
