What does fur scum mean in Portuguese, anyway?

What the heck were four protesters from PETA thinking when they crashed the runway at the Victoria's Secret Fashion Show, carrying signs that read "Gisele: Fur Scum" while supermodel Gisele Bundchen was strutting down the catwalk?

A. "Those edible undies better be made from soy beans."

B. "Use faux fur. It wouldn't be the only thing fake on these models."

C. "You want to know Victoria's Secret? She's at a greater risk for heart disease because her diet includes red meat."

D. "We were paid to do this by a brokenhearted Leonardo DiCaprio."

E. "We're … too sexy to arrest. Too sexy for your chest. So sexy … we … pro-test."

F. "We also condemn killing innocent fish to make fishnet stockings."
