When something is intense or truly awesome between 2 or more friends. Mostly used when one "Bro" scores with a hot chick or buys a new car. Used mostly by adolescents between the ages of 14-20.
Bro 1: "I heard you scored with Jessica in you new corvette!"
Bro 2: "Hell yeah! Right in her driveway!"
Bro 1: "That shit is The Balls Walls bro!"
