Here is another version of the story of the brigadeiro.

"I love brigadeiros, but let me tell you this story might not be right. It is rumoured that this name was created by someone who didn't like Brigadeiro Eduardo Gomes very much... it's about the fact that he had lost one of his testicles during the war (he was shot). Then people during the elections called the candy "brigadeiro" because it doesn't need an egg and "egg" in Portuguese is a slang for "testicle".
