Other forms: picadors
A picador is a bullfighter with a particular job: to jab the bull with a sharp spear, in order to get him angry and riled up.
You are only likely to come across the word picador in the context of bullfighting. There are usually two picadors on horseback who poke the bull with lances called picas to get him really mad before his confrontation with the matador, who is the main bullfighter. In Spanish, picador means "pricker" or "piercer," from picar, "to pierce."
