The phrase "pull rank" means to use one's influence or authority to get one's way. However, there are a few other phrases that can be used in its place. One alternative is "throw your weight around," which describes a more forceful approach to using one's position of power. Another option is "use muscle," which conveys the idea of physical strength being used to intimidate or dominate others. "Flex your clout" is also a suitable synonym, as it suggests a display of one's power and influence. Ultimately, it's important to remember that using one's rank or position for personal gain can be seen as unfair or unprofessional.
