malocorista
A person who acts out of line and kills the vibe at social gatherings, making them someone nobody wants around. They are usually a snitch, stingy, untrustworthy, selfish, and the type to hit on their friends women. (The term comes from coro, meaning a group of friends or a social hangout).
There is Pedro, do not call him over here because he is a total malocorista.
