En bloc means all together or as a single unit, like when a group of friends decides to leave a party all at once.
The term en bloc comes from French, meaning "in a block" or "as a whole." In a formal setting, a committee might approve several proposals en bloc rather than voting on them individually. This phrase can also apply to everyday situations, such as a family moving to a new house en bloc to ensure that everyone stays together. Using en bloc emphasizes a sense of unity and collective action.
