What does slipstream mean?
A slipstream is the narrow band of moving air or fluid that trails behind a moving object, such as a car, aircraft, or boat. A person or vehicle positioned within it can encounter reduced resistance and greater speed, which is why cyclists, runners, and drivers often use another vehicle's slipstream to conserve effort. The word also has a figurative meaning: an advantageous position that allows someone to benefit from the progress, reputation, or momentum of another person or organization. In this sense, a business may be said to remain in a larger company's slipstream, while a junior politician may benefit from a popular leader's campaign. Although the word can suggest a legitimate advantage gained through association, it may also carry a faintly critical implication when the benefit is substantial or the relationship is unequal.
A narrow stream of air or other fluid behind a moving object, especially a vehicle or aircraft; a position within this stream; or an advantageous position gained through association with someone else's progress.
"The plane flew in the slipstream of the aircraft ahead."
To travel in the airflow behind another moving object, especially to gain speed or reduce resistance.
"The cyclist slipstreamed behind the team car before making her move."
Used when referring to distinct airflows behind separate moving objects or to separate figurative positions of advantage.
"Several runners positioned themselves in the slipstreams of the cars ahead."
A slipstream is both a real stream of moving air and a powerful metaphor for catching a ride on someone else’s momentum.
