Arredondo rule 

whenever someone is speaking in generalizations, there is always an exception present. Based on the principle that there are always people around you that think that the norms do not apply to them, because they are special and one of a kind.
person to a group: "I read that you can't sneeze with your eyes open"

After making the statement, most people in the group will nod their heads in agreement, remembering the last time they sneezed...while there will be one person who claims that either they or someone they know always sneezes with their eyes open - That is the Arredondo rule.

Word of the Day on October 4, 2026
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.
