During sex with your significant other, you SLAP them so hard on the ass that their butt plug shoots out of their ass at Mach 5 and immediately lodges itself into your femoral artery. Your SO then drives you to the hospital while you "put a thumb in it" to plug your injury and stop from bleeding out, also known as a Kentucky Plug
Partner A: yeah, you like it rough don't you? *SLAP*
Partner B: *BOOOOM*... *ZIIIIIIIIP*... *BLOP*
Partner A: OH GOD ITS IN MY NECK! I THINK IT HIT AN ARTERY, I'M GONNA BLEED OUT!
PARTNER B: It's okay baby, just kentucky plug that hole while take you to the hospital.
When someone who is not acquainted with the proper way to apply a choke during sex via the means of applying pressure to the carotid artery instead just jabs their thumb into their partners throat as if they are Kentucky Ballistics trying to survive a SLAP to the throat.
Thot 1: Ugh, my boyfriend doesn't know how to choke me properly. He just jabs his thumb into my neck.
Thot 2: Ah, the ole Kentucky Plug.
