Backpfeifengesicht: A person who needs to be slapped; literally, "a face that needs a fist in it." A bit of a spoiler for The Amazing Spider-Man 2, kind of.
Peter sweeps Gwen into his arms and makes her face the bridge all strung with spiderweb, despite the death grip she has on his forearms (is she drawing blood? he wonders vaguely, as her nails dig into his skin) and her loud protests that she doesn't like being so high up, it's dangerous, they could fall, blah blah blah -
"Look, it says I love you, Gwe -" And then Peter stops, his mouth open in abject horror.
Gwen, cracking open an eye to look, sees the writing and gapes.
"You...you spelled my name wrong," she says in disbelief, reaching up and rubbing her eyes, all thoughts of danger forgotten as she lets go of Peter's forearms. "You spelled my name wrong!" she shouts, when, upon blinking, it really is true.
"Peter Parker!" she roars, and though they are hundreds of feet up from any other person, Peter thinks that all of Manhattan can surely hear her strident tones. "You. Spelled. My. Name. Wrong!" She punctuates each word with a stab of her perfectly French-manicured fingernail into his chest.
"I suppose now wouldn't be the time to ask you kindly if you might change your name to Gwem," Peter says, trying to make light of the situation, but Gwen is not amused.
She slaps him, and with a spinning momentum, whirling like a top, they both fall off the tower. As they rocket earthward, Gwen's screams and death threats in his ears and her fingernails definitely drawing blood on Peter's arms, he can only smile, press a hand to his cheek, and think about how lucky he is.
