Essentially mewing but with your buttocks. You squeeze your glutes at all times to shape it into a plump baby pumpkin carved from marble. Many clenchmaxxers have expressed feeling like they're in a higher plane of existance from performing this, not unlike gooning.

Flexing your buttcheeks at all time to both sculpt them into perfect marble-like bowling balls as well as boost your testosterone.
"Are you gooning right now?"
