The Vietnamese word "động đực" refers to the period when male animals are in rut, which is a time when they are ready to mate. This term is commonly used in the context of animals, particularly in agriculture or wildlife discussions, to describe their natural behavior during mating season.
In a more advanced context, you might encounter discussions about animal behavior, breeding programs, or wildlife conservation efforts where "động đực" would be relevant to understanding the reproductive cycles of species.
While "động đực" primarily refers to the rutting behavior of male animals, it can also metaphorically describe a state of heightened aggression or competitiveness among males in various contexts, including humans, though this usage is less common.
