Bruhism is a fast-spreading religion, in which the "God" is @Bruhssia on Instagram.

Rumor has it some so called "Bruhists" perform Bruhssian rituals to summon the God, yet all attempts so far have been fruitless. Also, Bruhism is an international religion that welcomes all sorts of people into their religion, but those who don't ship AmeriPan, (America x Japan from popular anime Hetalia), are considered a lower part of society based on ignorance to what must be the biggest ship in the navy.

Bruhism started on Sunday, January 25, 2015 in the morning, and proceeded to expand after.

Bruhism is now beginning to invade Tumblr, and most followers pray for it's popularity and support.
What's your religion? Oh, my religion is Bruhism, where AmeriPan is our main ship and @Bruhssia on Instagram is our Lord.

brycism (noun) by Ross October 7, 2006
Noun.

1) Strict definition: An irrational bias towards members of a certain orthodontic background. The bias can be positive (e.g. a braces wearer can prefer the company of its own kind, it's "Brace", or even another) or it can be negative (e.g. a person with orthodontic appliances can hate or resent others without). To qualify as Bracism, the bias must be irrational. That is, it cannot have a factual basis for preference.

2) Commonly intended definition(in America): A bias or intolerance that some people have towards those with orthodontic appliances.

3) Politically motivated definition: A justifiable reason to redistribute resources or opportunities between groups on the basis of braces alone.
1) Toby: "you wouldn't understand! I've had to eat wax! Just so I don't cut myself! (gestures to other "Brace" wearers) My people know what I'm talking about, why don't you go back to your own kind? That's Bracism bro"

2) Guy 1: "I wouldn't date her. Black and Decker Pecker Wrecker bro."
Guy 2: "You Bracist bastard"

3) Ray: "Shit, four peeps, only 3 pieces of gum. Nevermind, Toby, you have braces. You probably don't even like gum, right?"
Guy 3 and Guy 4: "Yeah, screw him, give it here!"
Toby: "Whatever, I'm out of here. Your all a bunch of Bracist bigots. Every hear of a little thing called The Progressive Orthodontist Magazine?"

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.
