en The Malespín is a kind of slang which originated in the 19th century in El Salvador and then spread to the rest of Central America. Tradition says that this slang was invented as a sort of key for the Salvadorian military and political leader Francisco Malespín. Broadly speaking, it changes some letters by others, as follows: a for e, i for o, b for t, f for g, p for m, and vice versa.
