MicroBro 

Just one of the guys, who just happens to be really short, a.k.a. "Vertically Challenged". That's all; he's just a short guy that hangs with you and your buddies. If he happens to be a niche beer fanatic, then it's a bonus: a double entendre.

There is nothing in this word that dictates the person's demeanor, so there could be microbros that are jerks, brainiacs, whatever.
The quintessential microbro is Holt Ann Richter, the character from The Cleveland Show. (voiced by Jason Sudeikis) - Holt attempts to be a suave, pop-culture reference-dropping bro, but the effect is undercut by his short stature (he is short enough to be mistaken for a child, as proven by Kendra occasionally referring to him as "the baby man")

Microbiomes 

Microbiomes are the longest known alien form of life. As in any life form, there are good and evil. Microbiomes aka aliens, are known for their voracious cannabalistic appetite. Crediting their mere exsistance to their unique ability to multiple at a rapid rate while feasting on other microbiomes. Human DNA is the prime rib of their main menu followed by your dog. The best line of defense agaisnst these resilient beings is to WASH YOUR HANDS!!!

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.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
