One of the main characters sticks his face into the crotch of one of the girls like a fucking dog, upskirt. She’s in love with him by the end.

Article from the actress who played her.

My mom also spoke up during the filming of that scene in “The Breakfast Club,” when they hired an adult woman for the shot of Claire’s underwear. They couldn’t even ask me to do it—I don’t think it was permitted by law to ask a minor—but even having another person pretend to be me was embarrassing to me and upsetting to my mother, and she said so. That scene stayed, though. What’s more, as I can see now, Bender sexually harasses Claire throughout the film. When he’s not sexualizing her, he takes out his rage on her with vicious contempt, calling her “pathetic,” mocking her as “Queenie.” It’s rejection that inspires his vitriol. Claire acts dismissively toward him, and, in a pivotal scene near the end, she predicts that at school on Monday morning, even though the group has bonded, things will return, socially, to the status quo. “Just bury your head in the sand and wait for your fuckin’ prom!” Bender yells. He never apologizes for any of it, but, nevertheless, he gets the girl in the end.

If you’re ever seen some variation on the last scene in the film, guy in a jacket triumphantly sticking his fist in the air with “Don’t You Forget About Me” playing, that’s the same character.
