Summative 

A universally feared report on a subject, often issued by Dr. Victory. Those who are assigned them often state emphatically they will start the weekend after being assigned it, though do not start until the weekend before. It is advised that one fills it with as much visual, textual, and quantitative data as possible, in the form of short, declarative sentences, with the purpose of causing >9000 victorgasms.
We were given about three weeks to do our final summative, but almost no one started until the week before. *D'OH*

Summitized 

Here is a term born from the wonderful people at summit racing. The people who love summit and think it is all that, and all good things for cars and trucks come from summit. Here is an example of how a "Tool's" brain works: dude I just went to summit and bought a cool air intake,splitfire plugs,accel coil,a k&n filter,hypertech chip,low temp stat,and headers w/daul exhaust for my 94 K1500. Now my piece of shit truck w/200k+ miles will go form 225hp to like 300+ hp, so in order to keep all that power under control I'm gonna need rancho shocks,rear sway bar,energy suspension bushings and some mickey thompson tires. This practice is also very common with small rice burning cars, like honda civics. These cars though need lots of colorful wire loom,painted dash parts,skull head shift knobs,and wings to make them faster.
Rich: I'm gonna drive to ohio to summit to get some parts for my truck, because no ordinary parts will do for my old K1500. Like some rancho"s, just thinkin of that summit store gives me wood!

Tool: True dat,I know the feel'in. I was just there gettin some stuff for my 89 civic!

Scott: So you two assholes esp. rich, just summitized your junk rides. Its like trying to polish a terd, or better yet flushing money down the toilet!

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.
