A head fake is a feint used in sports. A player moves their head to fake a change in direction and fool an opponent into reacting the wrong way. The term started in sports but is now used as a metaphor in other areas. In finance, a head fake describes a move where prices seem to go in one direction but end up moving the opposite way. For example, a stock might rise at first, suggesting it will keep going up, but soon reverses and falls. In 2007, Randy Pausch mentioned head fakes in his Last Lecture at Carnegie Mellon, explaining that parents often push kids to play football not to become stars, but to help them develop teamwork and social skills.
