McGarry Night 

1. A night where one drinks an insane amount of alcohol and will eventually pass out. Can be paired with Mega to make a Mega-McGarry night (for a night you will never remember and will probably end up in the hospital) or with Mini to make Mini-McGarry (for a night that you only get a little shit faced). Not to be used lightly.

Named for a certain Physics teacher who enjoys mean Manhattans and keeps a fridge in her room for "experiments" with ethanol. She also failed a Physics lab in college to go to happy hour.
1. Damn, it was a Mega-McGarry night last night. Shit man, what happened?

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.
