Rampant Douchebaggery 

When a person, who may or may not be a douchebag, commits several obnoxious actions that would make them seem as if they were on a douchebag rampage.

For instance, this person could all of a sudden pull out a pair of aviators, twist their cap backwards, chug a beer and attempt to crush the can on their forehead, then pump up some really loud bass beats and begin to fist pump.
Also, these people could simply be considered assholes and/or attention whores, who will go on a rampage by verbally annoying everyone around them if they are not being paid attention to, saying stupid things like "Yeah bro", "Yo, none of these broads are good enough for me", or "That's why everybody loves me man".

This makes everyone around this person want to inflict serious bodily harm to them, especially to their genitals, so that they cannot foul the earth with another little shit like themselves.
Person 1:"Oh my God, did you see that guy start fist-pumping at the bar after he chugged that beer? He almost knocked his stupid visor off his head-and how can he even see? He's wearing sunglasses indoors!"
Person 2:"Yeah I saw him..he's commiting an act of Rampant Douchebaggery right now. Just ignore him-these attention whores will calm down when they see everybody hates them."

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.
