el cuento del tío 6
It is a common name for any scam or deception where someone is convinced to hand over money in exchange for a promise that will later not be kept, or by appealing to their ambition by taking advantage of their unscrupulousness. The name comes from the story (in its meaning of "lie") most used at the beginning of the twentieth century, about a distant uncle who left a large inheritance but the nephew needed money to travel to collect, and he was going to share it with whoever would lend him for the passage and stay; And of course I never came back to pay. See "sell a mailbox", tocomocho, tongo, "put the cod", philately.
