To have something on one refers to the act of possessing incriminating or embarrassing information about someone, which can be used to manipulate or influence them. This phrase can also mean to have a task, responsibility, or obligation that one is expected to fulfill or complete.
In the context of possessing information, having something on one implies that an individual holds evidence or knowledge that could potentially damage a person's reputation, career, or relationships. This information can be used as leverage, giving the possessor power or control over the individual. The person who has something on another may use it to extract favors, obtain advantages, or enforce compliance.
Additionally, having something on one can describe being burdened with a duty or obligation. This could involve responsibilities within a personal or professional context, such as meeting deadlines, completing a task, or fulfilling an agreement. Having something on one can create a sense of pressure or a need to perform, as failing to fulfill the obligation may lead to negative consequences, such as penalties, loss of credibility, or damaged relationships.
Overall, having something on one refers to the possession of influential information or being burdened with specific responsibilities, both of which can significantly impact one's actions, decisions, and relationships.
