(chemistry orgy, chem party, chemistry party)
a gathering of AP chemistry students (cuz general chem is for n00bs), usually in an online chatroom, right before a major assignment is due i.e. a lab, a quiz, or a test.
Chem orgies consist of these students trying to organize an online study session. These "study sessions" usually end up as a bunch of kids in an online chatroom late at night spamming various questions concerning chemistry, and nobody really getting any answers. Very rarely is a chemistry orgy successful in its original purpose.

A candidate for a chem orgy must be verified before he/she partakes in said chem orgy, much like a normal orgy. An individual's intelligence, understanding of chemistry, amount of attention paid in class, willingness to share answers, and sex appeal. Despite the tedious chem orgy-goer selection process, this usually fails and the chem "study session" recedes into orgiastic behavior.

Not opposed to, neutral about, or actively-interested in the (usually mutual) use of illicit substances (ranging from "poppers" to marijuana to cocaine and many others) as an accompaniment or adjuvant during sexual activity. Often used in "profiles" posted on gay web-sites or in gay chat-rooms.

Math Chem is an intense chemistry course littered with complex math equations and impossibly described concepts that are specially designed to fry the average sophomore's brain. This class is one of the worst on earth, and the experience of math chem is made shittier by the presence of a bitchy teacher who yells at the class if one person doesn't know an ultra-specific piece of majorly overlaoded content that comes from exactly line 50 in chapter 15, section 12 to the left of Figure 15-30. Not knowing that will lower your grade, make your entire class fail, and will lead to suffering in and out of class for all of eternity.

Math Chem is an intense chemistry course littered with complex math equations and impossibly described concepts that are specially designed to fry the average sophomore's brain. This class is one of the worst on earth, and the experience of math chem is made shittier by the presence of a bitchy teacher who yells at the class if one person doesn't know an ultra-specific content that comes from exactly line 19 in chapter 15, section 7 to the left of Figure 15-34. Not knowing that will lower your grade by withdrawing 60 points where no amount of extra credit will save you, and your lack of bs knowledge will lead to your suffering for all eternity.
