(self care emergency medical technique)
The act of shoving your thumb in to an open wound to prevent bleeding to death after running slap rounds through your budget .50 cal and having it explode in your face. the maneuver was first popularized by Scott from Kentucky ballistics after his weapon blew up in his face.
Bro1: are you ready to test fire the AK50?
Bro two: yep I got my tourniquets, my safety googles and two Kentucky plugs. LETS DO THIS!!!
The act of sticking your left thumb into either a person's asshole, vagina, mouth, ear canal, or nares. This provides extreme pleasure for the "victim" and also for the person committing the act, as it is done in honor of the greatest human being on earth, Scott.
"I heard you and Jane got a little risky in bed"
"Yea, I gave her the good old Kentucky Plug last night, and she is in love with me again"
