a very bodacious butt
on a female. comparable to the term junk in the trunk
. in order for a girl to have hoofage you must be able to grasp her butt from the bottom of the cheeks and still have it overhang. a nice firm butt is preferable but as long as it looks nice this term is applicable.
When I see my girlfriend standing with just her panties im like damn she has some hoofage.
