The act of eating salty foods, and (ideally diarrhoea) shitting it out next day to get a salty sludge. This is to then use it in small doses to season the food of someone you dislike.
The unwritten or unspoken commandment for math educators worldwide not to conceal their weaknesses or deficiencies, or to pretend that they could figure out the answers by themselves; instead, they would be wiser to turn to their Creator, the Greatest Mathematician, for wisdom and insight to solve their logical, psychological, or mathematical difficulties.
If more math teachers, writers, or editors were to put into practice the “Thou Shalt Not Mask Your Math” commandment, they needn’t frustratingly spend so much time and effort in solving their mathematical ills, because the Holy Spirit could in a twinkle of an eye reveal to them the solutions, which would otherwise have taken them a hundred or thousand times longer to figure them out.
Ok, so Deuteronomy 1 states "Thou Shalt Not Deuteronomy or I Will Deuter On You Too." If you want to know what happens after that, it says "See Deuteronomy 2". Then it says to proceed on to Deuteronomy 3, 4 & 5 if they want to keep throwing it back and forth with you. Once you reach Deuteronomy 6, just keep on slingin' it until you're out of stock. I can live with that!
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.
