Sports team in the context of "Home field"

A rivalry is the state of two people or groups engaging in a lasting competitive relationship. Rivalry is the "against each other" spirit between two competing sides. The relationship itself may also be called "a rivalry", and each participant or side a rival to the other. Someone's main rival may be called an archrival. A rivalry can be defined as "a perceptual categorizing process in which actors identify which states are sufficiently threatening competitors". In order for the rivalry to persist, rather than resulting in perpetual dominance by one side, it must be "a competitive relationship among equals". Political scientist John A. Vasquez has asserted that equality of power is a necessary component for a true rivalry to exist, but others have disputed that element.

Rivalries traverse many different fields within society and "abound at all levels of human interaction", often existing between friends, firms, sports teams, schools, and universities. Moreover, "families, politicians, political parties, ethnic groups, regional sections of countries, and states all engage in enduring rivalries of varying length and intensity". Rivalries develop from the product of competition and ritualism between different parties. In some cases, rivalry can become "so consuming that actors worry only about whether their actions will harm or benefit their rivals".

Cricket is a bat-and-ball game that is played between two teams of eleven players on a field, at the centre of which is a 22-yard (20-metre; 66-foot) pitch with a wicket at each end, each comprising two bails (small sticks) balanced on three stumps. Two players from the batting team, the striker and nonstriker, stand in front of either wicket holding bats, while one player from the fielding team, the bowler, bowls the ball toward the striker's wicket from the opposite end of the pitch. The striker's goal is to hit the bowled ball with the bat and then switch places with the nonstriker, with the batting team scoring one run for each of these swaps. Runs are also scored when the ball reaches the boundary of the field or when the ball is bowled illegally.

The fielding team aims to prevent runs by dismissing batters (so they are "out"). Dismissal can occur in various ways, including being bowled (when the ball hits the striker's wicket and dislodges the bails), and by the fielding side either catching the ball after it is hit by the bat but before it hits the ground, or hitting a wicket with the ball before a batter can cross the crease line in front of the wicket. When ten batters have been dismissed, the innings (playing phase) ends and the teams swap roles. Forms of cricket range from traditional Test matches played over five days to the newer Twenty20 format (also known as T20), in which each team bats for a single innings of 20 overs (each "over" being a set of 6 fair opportunities for the batting team to score) and the game generally lasts three to four hours.

In politics, a defector is a person who gives up allegiance to one state in exchange for allegiance to another, changing sides in a way which is considered illegitimate by the first state. More broadly, defection involves abandoning a person, cause, or doctrine to which one is bound by some tie, as of allegiance or duty.

This term is also applied, often pejoratively, to anyone who switches loyalty to another religion, sports team, political party, or other rival faction. In that sense, the defector is often considered a traitor by their original side.

A fan or fanatic, sometimes also termed an aficionado or enthusiast, is a person who exhibits strong interest or admiration for something or somebody, such as a celebrity, a sport, a sports team, a genre, a politician, a book, a television show, a movie, a video game or an entertainer. Collectively, the fans of a particular object or person constitute its fanbase or fandom. They may show their enthusiasm in a variety of ways, such as by promoting the object of their interest, being members of a related fan club, holding or participating in fan conventions or writing fan mail. They may also engage in creative activities ("fan labor") such as creating fanzines, writing fan fiction, making memes, drawing fan art, or developing fan games. Some excessively avid fans are called "stans" (a portmanteau of stalker and fan).

A sports league is a group of individual athletes, sports teams or clubs who form a league to compete against each other and gain points in a specific sport. At its simplest, it may be a local group of amateur athletes who form teams among themselves and compete periodically, at its most complex, it can be an international professional league making large amounts of money and involving dozens of teams and thousands of players.

The Unified Team (Russian: Объединённая команда) was the name used for the sports team of the former Soviet Union (except the Baltic states) at the 1992 Winter Olympics in Albertville and the 1992 Summer Olympics in Barcelona. The IOC country code was EUN, after the French name, Équipe unifiée. The Unified Team was sometimes informally called the CIS Team (Commonwealth of Independent States, as a counterpart of CIS national football team taking part in Euro 1992 of the same year), although Georgia did not join the CIS until 1993.

The team finished second in the medal table at the 1992 Winter Games, and first at the 1992 Summer Games, edging its old rival the US in the latter.

Apostasy (/əˈpɒstəsi/; Ancient Greek: ἀποστασία, romanized: apostasía, lit. 'defection, revolt') is the formal disaffiliation from, abandonment of, or renunciation of a religion by a person. It can also be defined within the broader context of embracing an opinion that is contrary to one's previous religious beliefs. One who undertakes apostasy is known as an apostate. Undertaking apostasy is called apostatizing (or apostasizing – also spelled apostacizing). The term apostasy is used by sociologists to mean the renunciation and criticism of, or opposition to, a person's former religion, in a technical sense, with no pejorative connotation.

Occasionally, the term is also used metaphorically to refer to the renunciation of a non-religious belief or cause, such as a political party, social movement, or sports team.

In social psychology and sociology, an in-group is a social group to which a person psychologically identifies as being a member. By contrast, an out-group is a social group with which an individual does not identify. People may for example identify with their peer group, family, community, sports team, political party, gender, sexual orientation, religion, or nation. It has been found that the psychological membership of social groups and categories is associated with a wide variety of phenomena.

The terminology was made popular by Henri Tajfel and colleagues beginning in the 1970s during his work in formulating social identity theory. The significance of in-group and out-group categorization was identified using a method called the minimal group paradigm. Tajfel and colleagues found that people can form self-preferencing in-groups within a matter of minutes and that such groups can form even on the basis of completely arbitrary and invented discriminatory characteristics, such as preferences for certain paintings.

A sports club or sporting club, sometimes an athletics club or sports society or sports association, is a group of people formed for the purpose of playing sports.

Sports clubs range from organisations whose members play together, unpaid, and may play other similar clubs on occasion, watched mostly by family and friends, to large commercial organisations with professional players which have teams that regularly compete against those of other clubs and sometimes attract very large crowds of paying spectators. Clubs may be dedicated to a single sport or to several (multi-sport clubs).
