"Payed back spades" is a euphemism for settling a debt or getting revenge. Some synonyms for this phrase include getting even, reprisal, retaliation, retribution, vengeance, payback, and tit for tat. Other idiomatic expressions that convey similar meanings include giving someone a taste of their own medicine, an eye for an eye, and getting your pound of flesh. Each of these phrases implies a sense of recompense or repayment for a perceived wrong or injustice. However, it's important to remember that seeking payback can often lead to a vicious cycle of retaliation and counter-retaliation, so it's often better to practice forgiveness and find a peaceful resolution instead.
