The act of using your thumb to plug any orifice, while you SLAP the shit out of your partner. Inspired by a horrific shooting accident with ridiculously hot .50BMG Rounds.
Had to give 'em the KentuckyPlug, shove my thumb in 'er throat while I slapped her ass red.
A sex act wherein a man "stick a thumb in it," with "it" being a woman's vagina. Named after Kentucky Ballistics, a YouTuber who, when severely wounded, survived by sticking a thumb in his severed artery.
My wife loves getting a KentuckyPlug after a day of watching gun Youtubers
