A fight reportedly broke out during a recent screening of the new Barbie movie, after a parent reportedly let their child watch YouTube videos during it.
Greta Gerwig's long-awaited Barbie movie sees Margot Robbie take on the titular role of the Mattel doll, while Ryan Gosling plays her male counterpart Ken.
Fans have been waiting months to see the movie - which has reportedly grossed over $400 million at the global box office in less than a week since release - so it's understandable they'd want to be able to get immersed in Barbieland without any distractions.
However, cinemagoers ended up coming to blows in Brazil, after one woman apparently let her child watch videos during the showing, disturbing other film fans.
Footage shared by TikToker Sophia Ferreira appeared to show a woman in a pink blazer and checked shirt having a war of words with another woman a few rows ahead.
The lady in the pink blazer can be seen speaking loudly and gesticulating, even wagging her finger to make her point as the final credits rolled.
Things reached a head when the other woman came stamping up the stairs towards her, before apparently shoving the first woman in the face, with such ferocity that she fell backward between the seats, as gasps could be heard from others in the theater.
As a man tried to get between the pair to calm things down, the woman sprang back up and lunged towards the woman that had pushed her, with what appeared to be her shoe in her hand.
As the camera panned across, several people were seen still sitting in their seats, apparently mesmerized by the extra show they hadn't been expecting to see.
Thankfully, the pair ended up dispersing and viewers on TikTok who translated the argument from Portuguese to English revealed the reason for the fight.
According to their translations, one woman was annoyed at the other for letting her child watch YouTube during the film at "max volume".
And while it is pretty poor cinema etiquette to ruin everyone else's enjoyment of the movie by playing anything noisy on your phone, it's still not an excuse for violence on either side.
Film fans are always advised to turn their phones off at the start of a movie - or at the very least, turn them on silent and keep them in a pocket or a bag for the duration of the film.
As well as disruptive noises, the bright light glaring from a phone screen in the darkened room can also be quite annoying for others trying to get lost in the movie.
Despite one brawl (that we know of), Barbie has been doing extremely well at the box office in less than a week since its release, having racked up over $400 million globally.
Here's hoping all future screenings manage to go off without incident...
