hog
This word carries a heavy weight of gluttony and selfishness. When used for an animal, it is a descriptive agricultural term, but when applied to humans, it is almost always derogatory. It evokes an image of someone physically crowding others out to take everything for themselves. In social contexts, the term shifts from a literal animal to a behavioral critique. It describes a specific type of greed that is not just about wanting more, but about actively preventing others from accessing a shared resource, such as space, time, or attention.
Countable whether referring to the actual animal in a pen or a person who behaves greedily.
