Hours after the U.S. proposed 25% tariffs on Brazil, President Luiz Inacio Lula da Silva had found a way to seize on the threat.

He would brand it “TariFlavio,” after his top challenger in the country’s October presidential election: Flavio Bolsonaro, who met Donald Trump at the White House last week.

Lula’s campaign sent directives to allies, local party officers and supporters to blast the nickname across social media, according to a person familiar with the situation who requested anonymity. By the afternoon, “TariFlavio” was trending on X in Brazil, along with a phrase calling Bolsonaro “the enemy of Brazil.”
