Gooning

A session of intense "edging" that ultimately results in the person pleasuring themselves bearing the facial expressions of/looking like a 'goon', a ridiculous person, a fool, a human manifestation of a comedy of errors. The person's mind will be so overcome with euphoria from the edging that their facial expressions will fluctuate between a range of goofy and downright ridiculous. They probably will not be able to communicate with you beyond grunting like a wild ape.

Did you see his face while he was gooning? Guy looked like an absolute fucking retard!
