Guerrilla warfare is a form of irregular warfare and refers to conflicts in which a small group of combatants including, but not limited to, armed civilians (or "irregulars") use military tactics, such as ambushes, sabotage, raids, the element of surprise, and extraordinary mobility to harass a larger and less-mobile traditional army, or strike a vulnerable target, and withdraw almost immediately.

The term means "little war" in Spanish, and the word, guerrilla, has been used to describe the concept since the 18th century, and perhaps earlier. A person who is a member of a guerrilla is a guerrillero.

The term 'guerrilla' was used within the English language as early as 1809. The word was used to describe the fighters, and their tactics (e.g."the town was taken by the guerrillas"). However, in most languages guerrilla still denotes the specific style of warfare. The use of the diminutive evokes the differences in number, scale, and scope between the guerrilla army and the formal, professional army of the state.

The Young Bucks is an American professional wrestling tag team, consisting of real life brothers Matt and Nick Massie (also known by their ring names Matt Jackson and Nick Jackson) from Southern California. They are currently working for various promotions on the American independent circuit, most notably Chikara, Pro Wrestling Guerrilla (PWG) and Ring of Honor (ROH). They are also known for their time in Total Nonstop Action Wrestling (TNA), where they performed under the ring names Max and Jeremy Buck and the tag team name Generation Me (occasionally abbreviated to GenMe).

In 2001, the family put a wrestling ring in their backyard and the three brothers taught themselves how to wrestle by impersonating what they saw on television. At the age of 18 or 19 Matt began his professional wrestling training in La Mirada and City of Industry, California at the Revolution Pro Wrestling School called Rudos Dojo, training primarily under Ron Rivera (The American Wild Child), Disco Machine, Scorpio Sky and Super Dragon, among others. Matt attended the school with his good friend Dustin Cutler and the two would teach what they learned to their friends back home. Eventually Nick joined his brother and attended a few sessions at the school. Matt, Nick and Dustin would be involved in their very first professional match at an Alternative Wrestling Show/C4/Revolution Pro joint event that was held on August 8, 2004. Matt worked as Fluffy the Dog, Dustin dressed as a hillbilly and Nick was a high flying referee wearing a Santo mask. Soon after, Matt and Nick would wrestle various times for Revolution Pro and Revolution X (Rev Pro's darker counter-part) in chicken costumes, under the team name "Los Gallineros".
