Alice does something nice for Bob out of the goodness of her heart. Bob's response to that is to go "Oh, you did it wrong. But that's okay, I forgive you." Alice bristles at his audacity.
In a variant, instead of using the Stock Phrase, Bob may just let Alice know he doesn't blame her for something because it's not her fault she's useless at whatever she was trying to do in the first place.
Sometimes there is genuine misunderstanding somewhere in there. Sometimes Bob is just taking Alice too literally. Sometimes he's really that clueless. Sometimes he just thinks he's being funny. Sometimes he's genuinely being a Jerkass. This doesn't need to be intentional— it's only necessary that Alice interpret it this way: he has no authority to "lift blame" off her when whatever happened was not her fault in the first place, or it's something that's not even a real offense. That's why it's funny.
Other times, if the person being "forgiven" actually did apologize to the "forgiver", this could be used as a passive-aggressive way to accuse someone of Backhanded Apology. Done the right way, this form of forgiveness is one to which the recipient can't take offense without ipso facto admitting that their apology was insincere.
- Luo Hao in Campione! frequently forgives her opponents and allies for what she deems to be insults, weakness, or challenges to her dominance. She is so overwhelmingly arrogant that she views her forgiveness as a true gift. As an example, she has graciously allowed Godou's harem the privilege of looking at her without needing to then gouge out their own eyes for their impertinence.
- Monsters vs. Aliens: After dumping her earlier, Derek returns to Susan to forgive her, because "it wasn't your fault you got hit by a meteor and ruined everything."

- Taken to a global scale in Amadeus. Salieri attempts to establish himself as a Messianic Archetype, claiming the events of the movie as his sacrifice:
Salieri: Mediocrities of the world, I absolve you!
- In Cool as Ice, Kathy's fiance watches her dance with Vanilla Ice at a party, and afterward takes her aside and forgives her for it. This is meant to be seen by the audience as evidence that he's a pompous asshole and she'd be better off dumping him for Ice.
- In The Lost World: Jurassic Park, Dr. Malcolm lets Peter Ludlow know that "when you try to sound like Hammond, it comes off as a hustle. I mean, it's not your fault. They say talent skips a generation. So, I'm sure your kids will be sharp as tacks."
- In Mean Girls, when Ms. Norbury makes all the girls in school confront the fact that they've been mean to someone else, one girl apologizes to another girl for calling her a gap-toothed bitch, because "it's not your fault you're so gap-toothed."
- So not only is she "forgiving" the girl for being gap-toothed, she's only apologizing for half of the insult.
- From You've Got Mail:
Frank: Since when do you get manicures?
Kathleen: Oh, I suppose you could never be with a woman who got manicures...

- In Book Two (Fool Moon) of The Dresden Files, Lt. Karrin Murphy shoots in Harry's direction to save him from some crazy who was about to kill him. Harry, who was facing the opposite way at the time, hadn't seen his attacker and thought she shot at him instead, because she doubted his loyalties. However, he had previously betrayed her trust, so he decides he can't blame her for thinking him a bad guy and he forgives her for shooting him. Murphy thinks he's a big idiot for thinking that way, and lets him know it.
- Hazel to Anne in Anne Of Windy Poplars in her parting letter.
- Jade City: When Shae returns to her home city, her brother Hilo is quick to visit and tell her that he forgives her for having left the family. Since their estrangement happened when he reacted to her new relationship by calling her a whore and a race traitor and threatening to kill her boyfriend, she finds the gesture more than a little bit backhanded.
- From It's Always Sunny in Philadelphia:

Dee: Wow, thank you! That's my dad, everybody.
- From Sherlock:

- In The West Wing, after Josh and Amy have spent the episode in one of their usual semi-political-semi-personal power struggles, he comes up to tell her he forgives her for her side of it. She starts to take offense, but then Abbey prompts her to accept it for the sake of keeping the peace. She says in a monotone, "Thank you for forgiving me, Josh, I appreciate that," and then mutters, "Jackass."
- From The Goon Show:
Major Bloodnok: How dare you call me Major Bloodnok!
Seagoon: That's your name.

- A darker version is used in Ibsen's A Doll's House. Nora Helmer has borrowed money to send her seriously ill husband Torvald on a trip that saves his life. Unfortunately, the man who lent her the money (who is Torvald's employee) blackmails her that he'll tell her husband unless she gets him a promotion. After some complications, Torvald finds out what she did and snaps at her because the blackmail and her actions reflect badly on him (especially since she had committed forgery at some point). Then he finds out that the other man changed his mind about blackmailing him. He generously "forgives" her and gives her a good deal of the "you didn't know better" part of the trope. Nora coldly thanks him, but then she proceeds to give him "The Reason You Suck" Speech and leaves the house. The exit scene is described as the most dramatic doorslam in the history of theatre.
- In the Simpsons episode, "The Nedliest Catch", Homer convinces Ned that Edna's previous sexual encounters should not break Ned and Edna up when they were such a perfect couple. Ned invites Edna over to his place to apologize for freaking out, and then announces his forgiveness. They come down to a Make Up or Break Up and...that's the end of the season. The viewers vote for which happens. The viewers voted that they should stay together.
- In the Alvin and the Chipmunks episode "Funny, We Shrunk the Adults", Simon accuses Alvin of shrinking his lab coat. When it turns out that the coat belongs to one of Theodore's dolls, Simon snobbishly "accepts" Alvin's "apology", instead of apologizing for falsely accusing his brother.
