A sex act consisting of inserting one's thumb into any orifice of one's sexual partner; loosely inspired by an incident involving the YouTube Channel "Kentucky Ballistics" in which a .50 caliber rifle exploded as he fired it and he had to put his thumb into the injury on his neck to survive.
Hey bro, I gave that girl from the bar the KentuckyPlug last night and she loved it.
The sexual act of inserting foreign objects into your partner's throat either internally or externally usually performed after an object or body part has exploded in their face. Not limited to phalanges or other protruding body parts. Furthermore, any or all items from wish.com can also be tested for their "Kentucky Plugability". You're welcome Brandon.
