Backstroke

Unlike my poor mistaken friend who mistakenly defined the word as something else, I know what backstroke actually is. The perfect stroke, relying on actual physical strength, ability and will, unlike breastroke, which is dominated by three-foot tall dwarfs with no swimming talent and enormous feet. If you've actually watched swimming before, you know that it takes a sound backstroke leg to win the 400 IM or give your relay a win. Backstrokers tend to be more manly, and have fun playing games like "Dunk the breastroker."
Idiot Breastroker: OMFG ILY BREASTROKE! It's liek so kewl!
Me: Do you need help?
Idiot Breastroker: *Puts suit on inside-out* Let's do an 800 breast!
Coach: STFU.
Me: *Smiles*

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.
