Some people mistakenly believe this is a term for those over 18. Fraid not. Some people are born grown-ups, and some die at 100 never having acheived this status. If you are one, congratulations on not dying thus far; if not, here's some things you have to look forward to!

• You will cease to be impressed with your 1337speak, pwning people, your h4x0r rep and otherwise talking "liek u r" an illiterate moron. Intelligence, it's not just for breakfast anymore.

• For you emo kids, the world will get brighter for you when you stop crying and get another piece of ass. Life's cyclical in nature, roll with it.

• You will finally understand why your dad always screams when you begin to pay all your own bills. TIP: Pay electricity bill before buying the new GTA.

• Realizing that just because you CAN drink doesn't necessarily make it a good idea. Go out Wednesday, your place of employment might look like the jaws of Hell Thursday morning at 7:00 AM.

• Realizing that your place of employment ALWAYS looks like the jaws of Hell, shrugging and doing what you damn well feel like anyway.

and finally,

• The moment when you are truly no longer a kid, because you can't be. Because you have decided that all kids, without exception, SUCK. Because now YOU have a kid, crying, yelling, wetting the bed, wanting money. Karma's a cruel bitch.

Other than that, it's the only way to be... what else ya gonna do, be a 40 year old skateboarder?

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.
