Irreversible 

Controversial French flick released in 2002, directed by Gaspar Noe. Won the "Bronze Horse" award at the Stockholm Film Festival and was nominated for the Palme d'Or at Cannes. Also one of the most difficult movies to watch, due to a 9-minute rape scene and a guy getting his face caved in with a fire-extinguisher to some really creepy-ass music.
More than 200 people walked out of Irreversible at Cannes, mostly due to its lengthy rape scene.

irreversible consequence 

A consequence that cannot be reversed.
Some consequences are evitable, such as preventing or reducing the extent of an injury by wearing a seat-belt, or preventing a pregnancy by using a condom.

However, other consequences are inevitable, such as being disliked after saying something offensive.

And an irreversible consequence is one no one can go back in time and prevent from taking place because the action which produced it was executed.

The only way to prevent any type of consequence is by not executing an action (known to produce certain types of consequences).

Nonetheless, not doing anything might also generate some type of foreseeable or unforeseeable consequence.

Irreversible 

Something of which, once it has occured, cannot be changed nor undone.

Word of the Day on October 4, 2026
British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
