That period of time around the last couple weeks of classes and during exam week where you feel so overloaded and stressed that you would rather lay in bed with cookie dough ice cream and watch Family Guy than do anything productive. This is a very dangerous condition that may result in severe loss of motivation, feelings of helplessness, poor diet, weight gain, exhaustion, and the end of the world.

Semester Suicide 

Semester Suicide is taking a course load that will kill your social life and your happiness.

second semester senior

A victim of senioritis. Often displays symptoms of apathy, procrastination with the realization that it-be 'it' school, sports, whatever-doesn't really matter anymore. Second semester seniors can be found lying in bed, on facebook, at a party, or anywhere that requires the least amount of work possible. The most important question to a second semester senior is:
'Does it REALLY matter?'

Students are no longer considered a second semester senior once they have graduated, whereafter procrastination and laziness is their own damn fault.
A second semester senior may have been anybody before senioritis hit- an IB/AP whiz, stoner, that foreign kid- because senioritis will claim anyone and everyone as its victim.
yo holmes, i ain't doin my psych poll- im a second semester seniorrr.

A second semester senior receives an F for both achievement and effort.

I am writing this definition instead of filling out scholarship info.

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.
