Mulheres-a-foder-con-cavalos-gratis «QUICK ⇒»

Breaking down the words: "Mulheres" means women, "foder" can mean to have sex or to ruin, depending on context. "Cavalos" is horses. "Gratis" is free in Latin or Portuguese. So putting it together, it might be something like "Women having sex with horses for free." That definitely sounds inappropriate and potentially illegal.
