A method of penis stealth in which the man flips his boner up underneath his belt. However, the shirt must be kept down during this procedure or else the tip of his penis will become visible.

When an unexpected erection occurs, the act of tucking the boner upwards in its natural direction, held close to the stomach by the belt/ sweat pant elastic. Makes public erections virtually unnoticeable. A shirt is mandatory
