Biff wasn't feeling so hot after a 2 day bender with his lover, Sally Sue. He started to feel a little like a shell of himself, seeing shadow figures jumping around in the corners of his plane of sight. He figured it might be time to pack it in for a while and recoup. Alas! Lucky for him, he was hanging out with his friend Dick York who is hailed as the King of L&D! Lil Dicki told Biff that "Sleeping is for chumps! You can sleep when you're dead!" So, Biff ripped a few lines, slugged a few shots, and went back for round 3 of the bender and with his dank skank mami, Sally Sue, who was in the bedroom ass up ready to rumble again! Praise Be to the king of L&D!

L.D. Has an amazing personality. He knows how to have a good laugh and have a good time. He's always there to cheer you up when you feel blue. He cusses a bunch and even talks dirty sometimes, but he's super cool. And the one thing he will never do is let down his girl. He always lets her know he loves her and wouldn't do anything to hurt that.
Girl 1: That guy is such a L.D.
Girl 2: I know! I wish he liked me though!

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.
