The Aimoré (Aymore, Aimboré) are one of several South American peoples of eastern Brazil called Botocudo in Portuguese (from botoque, a plug), in allusion to the wooden disks or tembetás worn in their lips and ears. Some called themselves Nac-nanuk or Nac-poruk, meaning "sons of the soil". The last Aimoré group to retain their language are the Krenak. Wikipedia
