1o_ Relative to the bed . Who collects bosta as fertilizer or fuel. 2nd_ Nickname received by the supporters of the Boca Juniors football club (from the neighborhood of La Boca, Buenos Aires, Argentina), put by their main rivals of River Plate. Both clubs were born in the Riachuelo area that borders the south of the city, but River moved to a better one further north, in Palermo, which was not flooded with the southwest or covered with garbage (and bosta) when the waters were removed as in the Matanza-Riachuelo basin; hence the irony mentioned by Danilo Enrique Noreña Benítez to exchange "boteros" for "bosteros". Other nicknames are xeneize (bad pronunciation of zeneize) or the oldest pizza maker.
It was a way of offending The Boca Juniors fans. The word bostero means that he walks among the droppings of stables ( bosta ), either cow or horse. The term is used by rival fans in their chants. The original term was botero (boat) because there in the neighborhood of La Boca many people related to them, making them, painting them or driving them. It was required to pass the river daily (Arroyuelo). Today fans do not take it as an insult, but it is a source of pride and is like a brand of origin.
