Vivo
Someone who is sharp, clever, or quick-witted, but uses those skills to be opportunistic and take advantage of others or skip the rules. It describes a wise guy who thinks they are smarter than everyone else (often associated with the cultural idea of viveza criolla, where being cunning is used for personal gain).
You sure are a Vivo, give me my full change. / You really are a Vivo, put your name on the list and wait your turn like everyone else. / Don't try to be a Vivo with me, I know perfectly well that the job costs less than that.
