The test (which was first coined on tumblr) that monster-fuckers take when determining if they can fuck the fictional creature in questions or not. To be fuckable, the creature must:
1. Have human intelligence (or “greater”)
2. Talk or otherwise communicate with language*
3. Be of sexual maturity for its species.

If you answered yes to all of these questions, you may fuck the creature. If you answered no to any of them, you probably don’t wanna fuck it out of the possibility of beastiality or pedophilia.

*Body language is a dangerous road. Err on the side of caution.

This is an exclusive society in which the elite, sexually active members of Phillips Exeter Academy have sex on top of a harkness table (these auspicious tables are located in every classroom). This is a time honored tradition that no senior should graduate without. Now, that's something to think about during class.
Too bad I can't put " President of The Harkness Society" down on my college application.
