A strong or stupid person. Like someone on steroids or a caveman that can only grunt to communicate.

Horse Knuckles

The male equivalent of the female Camel Toes (i.e. when a man wears the crotch of his pants so high and/or tight that the seam splits, strangles and displays his genitals)

Eww, that guy is rocking those pants so tight he's got a raging case of horse knuckles.
