When you shove your thumb in someone's hole so hard, and with such stamina, that you literally stop them from dying.
It's a good thing Scott was able to Kentucky Plug himself, or else we'd have had to hear all about how his dad did it to him - that that would've been an even weirder boner.

When your girlfriend claims she can give you the "Kentucky Plug" it means she's a keeper, she's highly medically trained, and equally freaky XD so if anything happens I can guarantee she will put a thumb in it.
Woman: "hey baby, you wanna Kentucky plug tonight?"
Man: "of course! Ill go clean my barrel, and over pack my load"

Kentucky Plug is a sex act when one shoves their thumb up another's asshole or vagina. Was inspired by Kentucky Ballistics incident, where his RN-50 exploded and was forced to shove his thumb into his neck.

A term referring to the accident that Scott from Kentucky Ballistics had where he had to insert his thumb into his jugular to stay alive.
Damn you should see my girl, I gave her the Kentucky plug last night and she can't even walk in a straight line today

The Kentucky plug is the process of whilst giving your lady (or man if you play on a different team) so deeply that you busy a whole in their neck near the carotid artery and inserting your thumb (or their's if youre a real freak) and plugging that gaper up.
Scott from Kentucky Ballistics decided he would show his audience the Kentucky Plug move he learnt from his high school days to his audience
