A meme that was made in the dreams of a Reddit user, u/forzenny, where it was spammed on Twitter for seemingly no reason. The meme was popularized by YouTuber Matt Rose. The meme consists of a picture of a toy frog that changes color, with Papyrus font in lowercase saying "emergency frog situation," accompanied by a snippet of "We Are Number One" and Matt Rose yelling the same text into a megaphone.
Matt Rose, into a megaphone: "EMERGENCY FROG SITUATION!!"
We Are Number One blares in the background.
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.
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.
