Pariguayo
A socially awkward person, a fool, or someone who is boring and slow. The term is said to come from the English phrase 'party watcher', describing someone who goes to a party but only watches without interacting. It often refers to a man who is too timid to make a move on a woman he likes, even if she is dropping hints or they are sharing a bed. (Folk etymology in the Dominican Republic often attributes this term to U.S. soldiers who just watched locals during parties).
Maria likes Pedro, and Pedro likes Maria too, but he does not dare to say anything to her. Pedro is a pariguayo.
