Alice does something for Bob (most often this is saving their life)... then later Bob returns the favour, and one or the other will say "That makes us even" or "I guess we're even".
A malicious variant is when Alice wrongs Eva (or at least Eva thinks they did), and when Eva gets her revenge, she will say "NOW we're even"

- At least in Forgotten Realms, Drow has an interesting variation: they usually just don't get a concept of altruism, but Chronic Backstabbing Disorder is counterproductive more often than not, so what to do? Keep scores. Drow being more inclined to act for sport than out of obligations, it's not a score of debt, but a score in the "game".
So, what's the score now? Fyodor:
The score? Liriel:
The score. You know: I've pulled your tzarreth
out of the fire four times, you've saved mine three — that sort of thing. It says something, doesn't it?

- In Star Fox 64, if you save Falco in the asteroid stage, he will appear a bit later and kill a couple of enemies, telling Fox "that makes us even".

- A one-sided variant in Uncharted 2 Among Thieves from Nathan Drake toward Tenzin since they speak different languages.

- In Fallout: New Vegas, after helping out The King with a series of quests, he'll say that he owes you a favor, which you can cash in immediately for either a fake passport to The Strip, money or membership into his gang. However, if you hold onto it, during a quest where the NCR wishes to make peace with the Kings, you can use your favor to make him make him agree to settle things with the NCR, at which point he states that you're now even.
