A phrase referring to 9/11. This phrase is normally used by conspiracists that 9/11 was inside job carried out by the U.S. under President George Bush. The argument is that the steel beams that collapsed within the tower causing it to fall, could not have been melted by the heat from the collision of the plane. Meaning that the building could have been intentionally brought down via explosives, specifically using thermite, that can melt steel and leave no evidence behind.

Person A: 9/11 was such a mournful day in history. Screw Terrorists!!
Person B: Yeah....the terrorists are the government. Jet fuel can't melt steel beams.

Jet fuel doesn't melt steel beams

That "jet fuel doesn't melt steel beams" is a conspiracy theory based on 9/11. The name gives it away but it basically means the planes did not singlehandledly bring the towers down but someone had made them vulnerable on beforehand. There's also a conspiracy theory based on the twin towers not being built with steel beams in order to save money. "Jet fuel doesn't melt steel beams" is often associated with George Bush since he was the USA president at the time.

Jet fuel can't melt steel beams

A common statement by idiots who think 9/11 was an inside job. They say that the Twin Towers shouldn't have collapsed because jet fuel can't melt the steel beams that the towers were made out of. Although it's true that jet fuel can't melt steel beams, the Towers Collapsed because the steel beams were weakened from the fire, not melted. The conspiracy theorists are too retarded to realize this fact.

Idiot: 9/11 was an inside job done by George Bush!
Smart person: No it wasn't you fucking dipshit
Idiot: But... but jet fuel can't melt steel beams!
Smart person: The jet didn't melt the steel, it weakened it. Do more research, moron.

trucker's tan

A sunburn or suntan focused on the left arm. It is caused by the left side of the body being the only half that gets exposed to sunlight while driving. Presumably, it would be located on the right side of the body in countries where they drive on the left side of the road.

I had a trucker's tan after driving for 10 straight hours on a sunny day.

Boffin

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.
