There is a Brazilian saying that the soccer prodigy Neymar and his family often laugh about. The phrase — calça de veludo ou bunda de fora — comes up frequently: when Neymar reminisces about his beginnings in street games in São Vicente, for example, or when someone asks, again, “Are you really better than Messi?” Always, the family returns to calça de veludo ou bunda de fora. And then they all giggle.


The phrase is difficult to translate directly into English. Generally, it has to do with gambling and a man’s soul. It has to do with being brash and bold and brave. It has to do with fortitude and, perhaps more than anything else, an abiding belief in a singular path.


Sitting in a hotel lounge 25 stories above Columbus Circle in Manhattan last month, the star’s father, Neymar Sr., looked out over Central Park and tried his best to explain it. Across the Hudson River, his son was with the Brazilian national team, preparing for a sold-out exhibition match against Argentina and, beyond that, for the Olympics, where he will be the most dynamic player in the competition. At the London Games, with the world’s spotlight squarely on him, Neymar Jr. will seek to earn his country a gold medal, the one major soccer trophy it has never won.


“He is living it right now,” Neymar Sr. said. “That saying we talk about — he is doing it.”


But that was not enough. So Neymar Sr. tried again, through a translator, to summarize the essence of the phrase. His son’s success, he continued, has always been based on risk. On finding the right mix of fast and slow, of possibility and caution.


At 20 years old, Neymar is already the highest-paid soccer player in Brazil. He is the face (and future) of soccer’s South American mecca. He is, in the words of no less than perhaps the greatest player in history, a technical marvel, a wizard with magical feet. But through it all, his father said, this one Brazilian saying has guided him, especially now as the latest question — when will Neymar go to Europe for good? — is asked over and over.


Finally, Neymar Sr. laughed as he settled on the best way to present the idiom. He sat up straight and explained that in life there are, really, only two choices: “A man can either go through life wearing velvet pants,” he said grinning, “or he can go through life with his bare rear end hanging out in the open air.”


A Magician With the Ball


For the better part of 100 years, Brazilian custom has allowed many, if not most, people to go by a single nickname. This convention knows no boundaries (a former president was known simply as Lula), and in some cities even the phone books list residents by a lone name.


In soccer, the nicknames are prevalent. Edson Arantes do Nascimento is Pelé. Ricardo Izecson dos Santos Leite is Kaká. Robinho, who was Neymar Jr.’s favorite player growing up, is Robson de Souza. And so, before Neymar — Neymar da Silva Santos Jr., actually — there was Neymar Sr.


But Neymar Sr.’s risks did not come on the soccer field. Yes, he was a professional player, he said, but by his own admission “not a player of high quality.” In 1992 he was playing in Mogi das Cruzes, a factory city about 25 miles east of São Paulo, when his son was born. Initially, Neymar Sr. remained in Mogi, but after several years, as it became clear his playing career was ending, he moved his family — his wife, Nadine, as well as an infant daughter and Neymar Jr. — back to his hometown, São Vicente.


There, in the coastal city where he grew up, Neymar Sr. moved in with his parents. “We weren’t starting at zero — we were starting at minus-five,” Neymar Sr. said, acknowledging it would have been easy simply to stay put. Live in that modest house, raise his children with his parents around, aspire to little more than he had. “We could have done that,” he said.
