Bad Moon on the Rise 

Apparently, the top definition tells us it means when a girl's ass is hanging out of her pants.

Instead of using normal words to describe this, retarded people from the mean streets of harlem or whatever, decided to use some "urban" funky words. 99% of the slang that exists is fucking stupid, i mean, what the fuck is shizzle my nizzle, for the good of humankind, if you ever hear that phrase mutter, shove your fist at speed into whoever said it's mouth.

This is stupid, bad moon on the rise, is derived from the Creedence song, Bad Moon Rising. Its a phrase used to describe a bad omen, or bad things on the horizon.
When people bastardise normal words for such a stupid phenomenon, i see the Bad Moon on the Rise.

Yeah, shut up with your stupid made up slang, fuckfaces.

Bad moon on the rise 

(n.) -- the unfortunate view you get when a girl sitting in front of you is wearing very low shorts and a g-string or a thong.
Bad Moon On The Rise is actually a song title, but it fits this phenomenon because the "moon" refers to the girl's rear end, and the whole phrase implies that it's not a generally pleasant thing to look at.
"Ew, look at that girl!"
"Total bad moon on the rise."

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.
