Anytime you (or someone else) is trying to look casual but are secretly flexing in a picture or pose to make your muscles (usually arms) look bigger. This includes but not limited to, a hidden clinched fist to make your biceps look bigger, and also having your arms pressed against your body to make them look bigger.
Look at that guy, who is he trying to kid. His arms are not that big. He's just doing THE SILENT FLEX.

Uber flex is what happens when you and your brothers go out drinking and try to fight the Uber driver because he won’t let you in the car. Usually, one of the potential passengers takes off his shirt and flexes his muscles to show signs of aggression.
Apparently, U got hammered last night and started Uber Flexing on the driver who wouldn’t let you inside the car.
