Rotary

An Internal Combustion engine, popularised my Mazda in its earlier days. Makes distinctive buzzing noise, which can usually be heard from a distance. Uses a chamber with a spinning rotar inside to create driving force, and creats more power than a conventional piston engine for its size. Rotaries also have an annoying tendancy to have very poor fuel economy.

Robtor

Mythical creature known for it's bow legs, unique gait, long middle fingers, and dangerous mandibles.

It's been said that the Robtor often makes its presence known by a loud scream of its own name in the highest of possible pitches. Such a call has been known to inspire similar such calls by those around it and is also used to summon the Robtor at any moment. Generally unorthodox behavior ensues following such an appearance.
Person 1: "Robtor!"

Person 2: "Robtooooor!!!!"

rotary engine

To correct all of those that don't know, the rotary engine is an engine that was thought of by Dr. Felix Wankel when he was 17 and he made the first prototype of this type of engine, but sadly never perfected it (he never got rid of the chatter marks). Once Mazda got a hold of it and started working on it they perfected the engine, getting rid of the chatter marks and adding a second rotor because at low rpms a single rotor became erratic and had torque fluctuations. Also, the rotor is not shaped like a dorito, it's closer to one of those old 3d doritos (if you remember those) because it is an equilateral triangle with exploded sides.
You should do some research before claiming you know about the rotary engine.

Roton

Slang for a rotation student - a first year graduate student who rotates through a variety of labs before choosing the lab in which they will perform their thesis research. They are often abused, given scut work and mundane tasks that no one else wants to do. Combination of the words "rotation" and "moron". Similar to the compound word "touron".
There are also different kinds of rotons:
(1) The Fragile Roton ("I hope they like me - I will bring food one day or buy them coffee")
(2) The Overachiever ("Yes I will get a publication out of my rotation work.")
(3) The Bulldozer ("Move out of my way and I will show how science is done.")
(4) MuddFudd a.k.a MD/PhD ("Don't worry, I will always have medical school as my backup plan.")
(5) The Mute (...............sigh...........)
(6) The Kiss-ass ("Yes I agree you are so smart! What else can I do for you today?")
(7) Dr. Crick (His ego is so big and name drops like there is no tomorrow)
(8) Pigpen (leaves a dirt trail everywhere they go and you end up cleaning up after them)
(9) The Serial Killer (is super clean and organized and extremely accurate. Discovers things in your work you weren't aware existed. You worry he may kill you one day because you are so dirty and disorganized.)
(10) The Socialite (Always talking and shooting the shit. Entertaining but hard to motivate to do work.)
(11) The Mule (Works their tail off and you feel guilty for giving them more work. But you do it anyway.)
I have a roton working with me this term. He is a total kiss-ass so I am giving him the most boring experiments I can think of to keep him busy.
