Terminology used in multiple sports

A sophomore slump or sophomore jinx or sophomore jitters refers to an instance in which a second, or sophomore, effort fails to live up to the relatively high standards of the first effort. It is commonly used to refer to the apathy of students (second year of high school, college or university), the performance of athletes (second season of play), singers/bands (second album), television shows (second seasons), films and video games (sequels/prequels).

In sports, a false start is a movement by a participant before (or in some cases after) being signaled or otherwise permitted by the rules to start. Depending on the sport and the event, a false start can result in a penalty against the athlete's or team's field position, a warning that a subsequent false start will result in disqualification, or immediate disqualification of the athlete from further competition.

In sports, a losing streak or cold streak is an uninterrupted string of contests (whether games, matches, etc.) lost by a team or individual. A losing streak is thus the opposite of a winning streak. A losing streak can last as few as two games, or it may last much longer.

In several team sports, matches are played in two halves. Half-time (also written halftime or half time) is the name given to the interval between the two halves of the match. Typically, after half-time teams swap ends of the field of play, in order to reduce any advantage that may be gained from wind or a slope to the playing surface, for example.

A pre-game, pregame, or pre-match show is a television or radio presentation that occurs immediately before the live broadcast of a major sporting event. Contents may include:

In team sports, the number, often referred to as the uniform number, squad number, jersey number, shirt number, sweater number, or similar (with such naming differences varying by sport and region) is the number worn on a player's uniform, to identify and distinguish each player (and sometimes others, such as coaches and officials) from others wearing the same or similar uniforms. The number is typically displayed on the rear of the jersey, often accompanied by the surname. Sometimes it is also displayed on the front and/or sleeves, or on the player's shorts or headgear. It is used to identify the player to officials, other players, official scorers, and spectators; in some sports, it is also indicative of the player's position.

Penalty cards are used in many sports as a means of warning, reprimanding or penalising a player, coach or team official. Penalty cards are most commonly used by referees or umpires to indicate that a player has committed an offense. The official will hold the card above his or her head while looking or pointing towards the player that has committed the offence. This action makes the decision clear to all players, as well as spectators and other officials in a manner that is language-neutral. The colour or shape of the card used by the official indicates the type or seriousness of the offence and the level of punishment that is to be applied. Yellow and red cards are the most common, typically indicating, respectively, cautions and dismissals.

A jab is a type of punch used in the martial arts. Several variations of the jab exist, but every jab shares these characteristics: while in a fighting stance, the lead fist is thrown straight ahead and the arm is fully extended from the side of the torso. This process also involves a quick turn of the torso. It is an overhand punch; at the moment of impact, the pronated fist is generally held in a horizontal orientation with the palm facing the ground.

A throw-in is a method of restarting play in a game of football (or soccer) when the ball has exited the side of the field of play. It is governed by Law 15 of The Laws Of The Game.

Ball boys and ball girls are individuals, usually youths, who retrieve and supply balls for players or officials in sports such as association football, American football, bandy, cricket, tennis, baseball and basketball. Though non-essential, their activities help to speed up play by reducing the amount of inactive time.
