Cowboy Chemistry

Methods applied in a chemistry laboratory setting that are intended to cut corners and save time. It is also done frequently in poorly funded laboratories due to lack of materials.

Some examples include:

Sparging a solvent for an air sensitive reaction for 30 minutes rather than the recommended 1.5-2 hours.
Rinsing used glassware once with an organic solvent and reusing.
Choosing an acid/base on the basis of availability, rather than literature precedence.
Preceding to the next synthetic step without thorough purification.

Negative root causes for adapting these methods are typically hunger, tiredness, laziness or depression. On the other hand, these methods are often efficiently applied by those who have achieved a well developed intuition for the chemistries.

"Dude I am so hungry, I'm just gunna cowboy chem this work-up so I can get some taco-bell before they close."

"I told Dr. ______ my reaction didn't work because the starting material was oxidized, but honestly I cowboy chem'd the work-up and I think I decomposed the product."

"Rules are made so that the less adept make as few mistakes as possible. If you're smart you can do some cowboy chemistry to save a lot of time and materials."

"How did you finish the synthesis that fast?" -- "Cowboy chemistry lol".

AP Chemistry

the hardest f*cking class at del norte. Run by the laziest department of teachers I've ever seen. It takes 1 month for them to grade tests. You'll learn how to copy UT Quest answers and lab reports like an expert. Tests are so hard that they have a 50% curve.

I got a 20% on my first AP Chemistry exam.

How do I do stoich in AP Chemistry?
Feel lucky if you get a B in AP Chemistry.

the spawn of satan

I've been doing chemistry for the past 5 hours. It sucks ass. I'm going to kill Dr. White. My hand hurts.

chemise

A loose, dress-like undergarment worn by women under dresses and skirts. Also called a slip.

Spring is here; gone are the layers and heavier dress fabrics of winter, replaced by light chemise dresses.

chemistry project

Something usually done the weekend, or sunday, or day before it is due, with absolutely no work done on it prior. Often associated with random Urban Dictionary searches, music, youtube, laughter, that's what she said jokes, and pure procrastination. The affiliation with these items and/or actions are mainly wastes of time and complete distractions to the actual work, chemistry project.

"Dude, we have a chemistry project due tomorrow"
"Ok, lets get to work."
*searches the internet for hours upon end*
"Shit, we had a chemistry project"
"..."
