The Door Slams You

"Flora: Uncle Greeny, where are you?

Greensleeves: I'm under the door, ya twits!

Rod Rescueman: That's a pretty stupid place to be when people are knocking doors down."

- Twice Upon a Time

You've Seen It a Million Times. Character A is approaching a door, or is standing beside or in front of a door, when abruptly the door is thrown open from the other side by Character B. Character A is then revealed to have been squished against the wall by the door when it was smashed open.

While this is a type of Slapstick that is very common in animation, being hit by a door happens in live-action media also (not to mention real life). Definitely a case of Truth in Television: if you've ever seen a sign on a door warning you to open it slowly, chances are that sign was put up after someone got clobbered by that particular door.

Compare with Door Judo. See also Toyota Tripwire. Might be the deed of a Ghost Butler.

And no, this is not Soviet Russia. It might have happened there, though.

Anime & Manga

 * An early chapter of Mahou Sensei Negima has Asuna kicking the library door off its hinges, and into Negi.
 * Ranma One Half:
 * One of the few times that Shampoo uses the door to enter the Tendō house, she flattens Akane behind it.
 * Happens again to Akane when Ranma, in order to satisfy his mother's ideals of "manhood", burst into the bathroom to (pretend to) spy on her. Too bad Akane had come out several minutes before and was slammed quite painfully between the door and the wall... and hearing that Ranma wanted to see her naked did not improve her day.
 * And Ranma also did it to Kodachi in her own intro story just as the latter was about to attack Akane. She just twitched and spasmed behind the door for a while.
 * Sort of happens in the anime when Dr. Tōfū is introduced; startled by the good doctor appearing behind "her", Ranma leaps up onto the door. Akane comes barging in and slams the door shut, catching Ranma's fingers painfully between the door and the edge of the wall due to Ranma not having enough time to let go before being knocked out of the room.
 * Done in Naruto, when Suigetsu goes towards a door to try and find where Karin went... right as she gets back from finding there's a Leaf Village party headed their way -- and kicks down the sliding door on his face.

 * The Lupin III TV special Operation Return the Treasure had Goemon take up a position behind a door, ready to strike with his legendary sword, after hearing a noise in the hall outside.

 * An episode of the Black Cat anime has this happen to Sven as he's going out for a walk and Rinslet slams the door open just as he reaches it.
 * In book 4 of Futaba Kun Change, Principal Hiroin in one of his silly "Justice Maker" costumes is about to make the usual corny speech, when his daughter Takane slams open the door he was standing next and sends him down a flight of stairs (not that she notices anything, except the broken stairwell her father left behind as he fell down a few stories). And then Futaba-chan comes by in a hurry and slams the door against Takane as she was starting her own speech.
 * Neon Genesis Evangelion has an example where Shinji and Pen-Pen are having a Potty Emergency since Asuka occupied the bathroom. She then slams the door open, hitting Shinji in the face and buying Pen-Pen enough time to run inside before him.

An upset Lum pushes the door forcefully open and flies out to catch up to Ataru, but can't see him anywhere. A zoom in then shows that Ataru is flatened behind the door, his face ground into the wall.

Repeated both in the Animated Adaptation and the Live Action Adaptation Astérix & Obélix: Mission Cleopatra.
