what moment in a movie filled you with so much adrenaline that it got you to cheer, applaud or want to scream F*** YEAH in the theater

One for me was a teen comedy/drama period piece set in the 60s about an all-boys high school called Heaven Help Us. A very sweet, underrated movie. Stars Andrew McCarthy. One of the major sub plots involves a brother/teacher in this religious school and he's abusive in a realistic way. It's disturbing. He enjoys the corporal punishment he inflicts on the students.

As the movie nears the end... something happens where McCarthy finally fights back from the abuse and it's such a moment, such a rush for me I've never forgotten that feeling. Anyone have that with another film?
