Kharkhuwa
Kharkhuwa or Kharkhowa is an Assamese term which is used to signify a person necessarily having Assamese ethnicity and a descendant of people of medieval Assam, now a territory of India.
The word Kharkhuwa has found its use extensively in Assamese satirical ( but sometimes even in serious) pieces of writing and in common parlance to signify native and indigenous commoners of Assam, often referring to or addressing them in a derogatory manner but never being offensive in any way. In fact, this word is a privileged term, loved to be used by a person referring his or her own self with pride for being a native Assamese speaking commoner.
