Cold Call or Bet
A "cold call" refers to the calling of bets made by multiple players, such as happens when one player bets, another raises, then a third calls the total amount "cold." E.g, "Fred opened for $20, Gary raised to $50, then it folded to Hank who cold-called the reraise."
A "cold bet" or "cold raise" similarly refers to a raise made against multiple players. E.g., "Fred opened for $20, Gary raised to $50, then it folded to Hank who cold four-bet to $100."
