The kentucky plug

The act of using one's thumb to plug an orifice, wound or hole on a body (one's own or another person's), that is gushing with liquids that should not be gushing in the first place; making it a viable maneuver for both the stopping of the release of feces during sexual intercourse and/or severe bleeding from a gunshot wound.

AR guy: yeah, but I heard he used the ol' The kentucky plug, so he didn't bleed out
