When you need to, for whatever reason, plug a human orifice with your thumb. Sometimes you need to Kentucky plug the hole in your neck that is rapidly leaking blood. Other times, you need to Kentucky plug your girlfriend's asshole because it's Tuesday and you haven't plugged it since Sunday and she's itchin' for a pluggin'.
