The sudden, and often timely, understanding of a subject, usually in school. Most commonly paired with a loud exclamation of "OHHHHHHHHHHH! I GET IT NOW!" or something very similar. Usually done by the less studious members of the class, who understand it right before a test or quiz.

It is a type of orgasm acheived from mind. Sexual arousal is physical and mental—but if one tries hard enough, our thoughts really are all we need to get off.
Some people can actually ‘think’ themselves off through fantasy and breath work.
These are sometimes called “energy orgasms,” because the method requires developed brains. Orgasms from “thinking off” show up in the same spot of the brain as orgasms from genital contact.
