Mantero is that it sells traveling for counterfeit products such as music CDs, commercial video DVDs and video games, clothing, watches and other imitation products; materials that, when sold, infringe the copyright in force in that country, therefore the activity is illegal and punishable by imprisonment. People dedicated to it are called manteros
In Colombia he is a person who risks going out during the corralejas to a ring, to a blanket, a ruana, a poncho or piece of rag, take several spears out of a brave bull. This is very common in the festivities of the coastal villages, usually done under the effects of alcohol and almost always in order to obtain a cash prize.
MANTERO , I deeply disagree with the lack of editorial judgment of the dictionary with regard to the words to be defined. Enter, for example, mantero , mantera , mantero mantero , mantero-ra , manteros , manteras generates potentially 6 entries for the same word, artificially and negatively enlarging the size and, worst of all, complicating and lowering the quality of the search and the information delivered. That said, mantero is a blanket manufacturer or seller.
