Definition & Meaning of "follow suit"

What is the origin of the idiom "follow suit" and when to use it?

The idiom "follow suit" originates from card games, specifically from the game of bridge. In card games, a suit refers to one of the four categories (hearts, diamonds, clubs, spades) into which a deck of cards is divided. When a player is unable to play a card of the leading suit, they may choose to play a card from a different suit, but it is generally expected that the other players will "follow suit" by playing cards from the same suit as the leading card. Figuratively, this expression is commonly used to describe situations where individuals or entities mimic or imitate the actions, decisions, or behaviors of someone else.
