What does steamroll mean?
Steamroll means to crush or flatten something with a steamroller, but its figurative use is more common today. It describes defeating an opponent overwhelmingly or forcing a proposal, decision, or campaign through with such force that opposition has little practical effect. Expressions such as "steamroll through" and "steamroll the opposition" are particularly associated with politics, business, and competitive events. The word carries a strong implication of irresistible power, rapid progress, and the sidelining of resistance rather than merely winning. In its literal sense, it refers to the use of a heavy, powered machine to level a surface. The figurative meaning developed from that physical image of something powerful moving forward and flattening whatever stands in its way.
