push (one's) weight around
To assert oneself in a controlling, domineering, or authoritarian manner; to exercise one's position of authority, power, or influence, especially to an overbearing or excessive degree. An effective leader should inspire enough confidence in his or her team that they don't have to push their weight around to get things done. I'm sick of Donald coming into these meetings and pushing his weight around. Can't he just leave us to our own devices?
