Boom Cup 

A drinking game for a larger group of players than typically used for beer pong. Usually works best with 10-15 players.
SETUP: Place about 30 cups in a cluster in the center of a large table (about ping pong size). Fill each one about 1/4-1/3 of the way with beer. The cup in the very center will be the last to be drunk, and it should be filled to the top with beer or a random combination of drinks. This is known as the "bitch cup". Two more empty cups and two ping pong balls will be needed.
GAMEPLAY: Two players far apart from one another each have one of the empty cups and ping pong balls, and they attempt to bounce the ball into the cup. If they succeed first try, they can choose who to pass the cup/ball to next (typically the person to the right of the other person currently trying to bounce a ball into their cup). If the first attempt is not successful, the player continues trying until he is successful, then he must pass it to the player on his left.
If two adjacent players have cups/ping pong balls at the same time and the player on the right makes the shot first, he can then stack his cup on top of that of the player to his left. This player must pass the stack of cups to the player on his left, then pull one of the cups from the middle and drink it. This is his new bounce cup. Play then resumes once again. Eventually only the "bitch cup" will be left. The person to get "stacked" by the player on their right when only this cup remains must drink this entire cup!
Guy 1: "We tried to play beer pong when we were preganing but there were just too many people and games took too long."
Guy 2:"You should try this new game I know, called Boom Cup! It's fun and fast-paced and lots of people can play!"

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.
