It’s common knowledge that our minds are great machines, held together by nuts, bolts, and screws. Factory-made and tested for quality, our minds can withstand a lot of stress. Day in and day out these machines handle mundane tasks and monumental problems with relative ease. Unfortunately for some, too much stress will cause the machine to fall apart. This is known as, “having a screw loose.” The Cuckoo Sign is a pretty simple way to indicate that someone’s machine is messed up and they need one of their screws tightened.
This gesture can refer to oneself or another person to mean, “This person is crazy.”
