Tohono O'odham
The name Pisinemo is actually a failed attempt by the Motor Vehicle Division to put the traditional name of Pisin Mo'o onto road side signs along Highway 86 which runs through the Tohono O'odham Nation. Pisin Mo'o is Tohono O'odham for "Buffalo Head". (The O'odham pronunciation of "Pisin Mo'o" is approximately , which is relatively close to the Anglicized spelling.)
