When your girlfriend gives you a look of disapproval or rage. This look can be incurred before or after committing the "crime". Similar to the Stink eye but with a hint of madness.
I was checking out this chick when my girlfriend saw me and gave me the mad eye.

When someone imitates or impersonates another person (real or made-up person), namely on social media, just to spy on their crush, an estranged relative, past friend(s) and other sorts of people, either to see what they're up to or to lust over them. To put it simply, if you create a fake account to spy on a few people, you're a Mad Eye Moody Eye.

This is based on the Harry Potter character Moody Eye in The Goblet of Fire, who was actually Barty Crouch Jnr impersonating him to spy on Potter and see what he is up to.
- My ex left me and married another. How should I catch up on him on social media when his profile is private? :(
- Just make a fake account and pretend you're a local priest or some politician from his favourite party and add him, hon.
- Oh, that's a good idea. Very Mad Eye Moody, huh? :P

A physical ailment, usually exhibited by the overly tired or the extremely drunk, wherein one eye of the sufferer seems to wander aimlessly while the other eye remains fixed on the target of interest.

This unfortunate condition is typically environmentally induced and should not to be confused with the naturally occurring 'lazy eye' attributed to weak eye muscles.

The term refers to the Harry Potter character named Mad Eye Moody who possessed one magical eye that could scan the surrounding for Death Eaters, including above and behind the wearers line-of-sight.

Maisie, commonly referred to as "mad eye", is the name given to one distinct ginger. Often noted for her sudden interest in hand gestures along with the usage of two Italian words., the name Maisie actually means "Greek Margarita". Also known as "Kelly", mad eye is truly versatile in what she can accomplish and therefore is destined to become a spy for the CIA and USSR. Mad eye Maisie can be spotted out of a crowd due to her ginger hair(described as a rose in Goolia's famous poem) that is often paired with a nonchalant hair clip.
