When Brazil was discovered, in the coast there was aborigenes that say to be Tupinambás (of the Tupi, "true men"). Tupinambás were a ferocious tribe, semi-nomadic that practiced the anthropophagy and it lived in state of permanent war against the other natives (Tupis, Potiguaras, Guarulho, Tamoios, Tabajaras, Caetés etc...) and obviously against the Portuguese.
The Americans resemble a lot the old Tupinambás. They are always wandering in search of their enemies. They are ferocious and they say that they are the "true men". And in the last times the anthropophagy was common in the USA (even in the movies).
How should we call the Americans now? Americambás or Tupinamericans?
