A way to describe someone physically built in a way similar to a fire hydrant, such people are usually a bit shorter, yet solidly built and wide in the shoulders, but not fat. If they are fat they become a tank. Such people usually have good balance, thick necks, a low centre of gravity, and strong momentum behind their punches, and are usually deceptively strong, as seen in MMA fighters such as Matt Hughes and Sean Sherk.
Sen Dog from Cypress Hill is a classic example of a fire hydrant build. I wouldn't fuck around with him if I was you.
