Mississippi Leg Hound
A very horny dog that looks at your leg and thinks it is a prospective mate, then hump away like there's no tomorrow with the lipstick fully extended.
Cousin Eddie: "Only problem is he’s got a little bit of Mississippi leg hound in him. If the mood catches him right, he’ll grab your leg and just go to town."

Mister, I can't get any yard work done if you don't chain up that Mississippi leg hound.
