look up any word, like fleek:
 
1.
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.

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. Often cocky with a large ego, and spends large amounts of time leaving their laptop at their desk while going out to lunch or on coffee breaks. Often corrects or insults more senior students, only to ruin their future possibility of joining the lab, or may be found kissing an enormous amount of ass in order to secure a spot in said lab.
"I can't wait until the roton leaves at the end of the semester; he barely made any progress on his research, since he spent so much time flirting with the lab tech."

"Our roton might join our lab at the end of the quarter, since our advisor needs some new cheap labor to finish up that project."
