Shirts and skins意思
"Shirts and skins" is a term commonly used in sports, particularly in basketball, to indicate the division of players into two teams for a game or practice session. One team wears shirts (usually the home team or the team that has prepared jerseys), while the other team plays without shirts or with a different color of shirt (often referred to as the skins team). This method is often used when there are not enough jerseys for everyone or when players are divided into teams on the spot without the need for separate uniforms.
