The Kentucky Plug is a sex position in which a person shoves their thumb into their partner effectively stopping any fluids from exiting the hole. (Note that this is also the life-saving position the YouTuber (Scott) Kentucky Ballistics used on his shoulder to save his life after having an incident with a hot SLAP round detonating his firearm, and hence the name of this position in tribute to its creator.) "JUST PUT A THUMB IN IT!"
Person 1: I had fun last night.
Person 2: oh? what did you do?
Person 1: I gave my wife the Kentucky Plug!
Husband: Wife do you wanna try something new tonight?
Wife: JUST PUT A THUMB IN IT!
Husband: ah, the Kentucky Plug!
