In combat sports and hand-to-hand combat, a kick is a physical strike using the foot, leg, or knee (the latter is also known as a knee strike). This type of attack is used frequently, especially in stand-up fighting. Kicks play a significant role in many forms of martial arts, such as Taekwondo, Karate, Pankration, Kung fu, Vovinam, Kickboxing, Muay Thai, Capoeira, Silat, and Kalarippayattu.

The English verb to kick appears only in the late 14th century, apparently as a loan from Old Norse, originally in the sense of a hooved animal delivering strikes with his hind legs; the oldest use is Biblical, in the metaphor of an ox kicking against the pricks.

The act of kicking in general is a universal form of human aggression. The same movement is also used in non-offensive contexts, e.g. a kick to propel an object such as a ball, or a kicking movement without touching anything, e.g. as a dance move.

Kicks as a form of attack are more typically directed against helpless or downed targets, because using a kick in a combat situation bears the significant disadvantage of losing stability of one's stance, as delivering a kick obviously requires lifting at least one foot off the ground.

"Pumped Up Kicks" is a song by American indie pop band Foster the People. It was released as the group's debut single in September 2010, and the following year was included on their EP Foster the People and their debut album Torches. "Pumped Up Kicks" became the group's breakthrough hit and was one of the most popular songs of 2011. The song was written and recorded by frontman Mark Foster while he was working as a commercial jingle writer. Contrasting with the upbeat musical composition, the lyrics describe the homicidal thoughts of a troubled youth.

The track received considerable attention after it was posted online in 2010 as a free download, and it helped the group garner a multi-album record deal with Columbia Records imprint Startime International before they had issued a commercial release. The song became both a crossover hit and a sleeper hit in 2011, as it received significant airplay on modern rock and contemporary hit radio stations. The song spent eight consecutive weeks at number three on the Billboard Hot 100 chart in the United States, making it the first Billboard Alternative Songs number-one single to crack the U.S. top 5 since Kings of Leon's "Use Somebody" in 2009. The song was widely praised by critics, and it has been licensed for use in a wide range of popular media since its release. "Pumped Up Kicks" received a Grammy Award nomination for Best Pop Duo/Group Performance.

Paul Revere (December 21, 1734 – May 10, 1818) was an American silversmith, early industrialist, and a patriot in the American Revolution. He is most famous for alerting Colonial militia of approaching British forces before the battles of Lexington and Concord, as dramatized in Henry Wadsworth Longfellow's poem, "Paul Revere's Ride."

Revere was a prosperous and prominent Boston silversmith, who helped organize an intelligence and alarm system to keep watch on the British military. Revere later served as a Massachusetts militia officer, though his service culminated after the Penobscot Expedition, one of the most disastrous campaigns of the American Revolutionary War, for which he was absolved of blame. Following the war, Revere returned to his silversmith trade and used the profits from his expanding business to finance his work in iron casting, bronze bell and cannon casting, and the forging of copper bolts and spikes. Finally in 1800 he became the first American to successfully roll copper into sheets for use as sheathing on naval vessels.
