Derived from the fictional character, Lily Potter. A woman who already has a man in her life who is prefect for her. Someone who loves her more than anyone and treats her better than anyone else but she constantly leads him on only for him to be violently thrown into the friend-zone time and time again, treats him like dirt and never notices what he does for her or what he goes through for her. A Lily will always choose a man who is bad for her over the only one who actually cares.
I don't care about you anymore. Not after noticing you were a Lily.

Frog on a Lily 

A smoking term. A Frog on a Lily is a piece packed half-way with green then a thick strip of hash on top. Use enough hash to just barely cover the top. Instead of a wrap A Frog on a Lily is only used with Water Pipes and Bubblers. The term is derived from a "Snake in the Grass", a rolled out line of hash in a joint or blunt, but the hits are more phenomenal this way.
Cheryl: How are we going to mix this hash with weed

David: We could make a Snake in the Grass but we only have this bong.

Cheryl: Let's just pack it half-way then put it on top.

David: Oh shit, it looks like a Frog on a Lily!

Cheryl: (Lighter flick) That hit just took something out of me. I've never felt a sensation so astounding.

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.
