hoss wobble
The distinctive gait of a morbidly obese person walking, where the sheer quantity of extra lard being hauled around requires the rotation of the entire torso with each forward step. This results in a precarious looking gait, similar to waterfowl waddling on dry land.
Holy shit! Check out the hoss wobble on that broad. I bet she goes 3 spins! You'd have to roll her in flour and aim for a wet spot!
