A spin off of the phrase "jet fuel can't melt steel beams," referring to the tragedy of 9/11 where conspirators say that it must have been an inside job for this reason. To shame this phrase, it has become a meme of sorts and people use it jokingly. The replacement of the word "beams" to "memes" was simply further fuckery with the phrase.
"We shall now bow our heads in a moment of silence for those who lost their lives on this tragic day."
*voice in the crowd* "Jet fuel can't melt steel memes ,"

*conspirators chanting* "inside job. Inside job. Inside job. Inside job..."
