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.

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.
1. When you are arguing with someone who has a seemingly air-tight argument and you blow a load of philological wisdom into his argument.

2. any kind of come back.

3. A literary ejaculation
Joe: 9/11 was clearly the work of Osama bin Laden (and proceeds to show you undeniable proof) Zack: Oh Yeah, well Jet fuel can't melt through steel beams!

Pat: WTF you ate all of my Nutella!

Asshole who ate his Nutella: WTF dude, Jet fuel can't melt through steel beams ergo I did not eat your Nutella

Chemistry teacher: Mr. Erickson will you please tell the class why covalent bonding is different than ionic bonding.

Andrew: Uh because Jet fuel can't melt through steel beams.
