Calldowns typically mean actions taken to challenge the bets of an opponent, but there are a few synonyms for this term. One such term is the "call station" which refers to a player who frequently calls their opponents' bets. Other synonyms for calldowns are "calling station" and "sticky player." These terms suggest that the player may not be making optimal decisions and may be overvaluing their hand. In contrast, "loose call" refers to a player making a call with a weak hand. In summary, while calldowns generally involve calling an opponent's bet, each synonym offers a slightly different nuance to the concept.
