Etymology
The coined term has two possible, disputed origins. The first disputed origin is that the term is derived from the word pinol, a form of toasted ground corn that is the main ingredient for Pinolillo, a powdered form of the pinol which is used in a variety of local cuisine and beverage preparations. Historically, indigenous tribes in Nicaragua depended primarily on corn-based products as their primary food staple.
The second disputed origin is that the term comes from the Pinolero van-pickup truck hybrid model produced by the state-run Nicaraguan Industry of Vehicles (known as Industrias Nicaragüenses de Vehículos, SA or INDEVESA in Spanish) during the 1970s. These vehicles were a source of national pride because of the attempts to industrialize with state-run resources.
