“A bet’s a bet” is a colloquial expression that means a promise or agreement, especially one involving money or something of value, should be honored once it has been made. It emphasizes the importance of keeping one’s word and fulfilling the terms of the bet, regardless of the outcome or any subsequent change of heart. It’s a way of affirming that the agreement should be respected and acted upon as originally intended. This phrase is often used in informal settings among friends or in situations where the stakes of the bet are not overly serious.
