The 2% rule is a reference measurement noting the relative amount smarter you need to be (or think) to be able to pull off a particular task.

Frequently used as a gentle insult or to point out someone's apparent stupidity, usually in direct reference to a task said person is presently trying to accomplish. Typically but not limited to involving the use or inability to use a piece of technology.

A rule that states that if a food item sounds 2/3 good, it must be good.

Originated at a Taco Bell, whereupon the creator was deciding whether or not to buy a Caramel Apple Empanada. The creator had no idea what an empanada was, but caramel and apple made it sound 2/3 good. The Caramel Apple Empanada turned out to be delicious, and thus the 2/3 rule was born.
Indecisive customer: "What's fried chocolate guano?"
Friend of indecisive customer: "I don't know, dude, but it sounds 2/3 good. By 2/3 rule, you have to try it."
