I dated a girl from Flat Rock last year, she was white trash and her dad was a Walmart Wolverine. But at least she put out.
Flat Rock by TicklemeEmo October 10, 2005
A very small town in southeastern Michigan that has a total area of only 6.8 miles. For a very small town it is actually pretty busy on Telegraph road where their are a variety of fast food restaurants and the Flat Rock Speedway and a bowling alley, it also has a driving school where most of the crappy drivers in wayne and monroe county learn to drive. It also has an abandoned K-mart which looks like hell with weeds growing all over the damn place. The high school is a small school full of white trash, wiggers, blacks, and emo's. And when I say emo's I mean emo's just a ton of them. So to put it simply Flat Rock is a very small town with many residents below the poverty level and very odd kids.

Friend: "Ugh emo kids they must be from Flat Rock.

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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
