Braintree 

Where everyone is either a yahhh dooood, a skanky ass hoe, or a pothead. Thinking about getting shitfaced is the only thing that keeps you motivated throughout the school week. People know about your weekend before Monday even rolls around. W"The Bridge", "The Rock", "The Outback", "The Beach Spot", "Party to the left", "GMa's House", "The Dam", "The Spot", "The Craitor", etc. are the places to be. You can find Mr. Swanton & Friends running around like madmen @ BHS on their walkie-talkie's. In order to fit in you must own maximum articles of Abercrombie&Fitch. Common words such as "ruueee" "geeeek" "reeeep" and "dudeee" are used excessivly. Instead of saying "ummm.." in between your words, you say "fuckkinnng.." Braintree's football team is MUCH better than Weymouths. You technicaly wouldn't even need to shower during the school week, you could just stand under one of the leeks in the ceiling of our school. We live by the PRIDE statement...Freshman girls are gaurenteed multiple bitching outs. You automatically look like a slut for wearing a skirt, and to make it even worse Mrs. Kelly WILL find you. Here in Braintree you can find drama any time and place.
dude, go call Ryan from Braintree..his weed's mad goood.

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.
