The Kentucky Plug is the act during sex of using your thumb in order to stop a girl from squirting, much as Scott stopped his neck from squirting.

Commonly referred to as the thumb, the Kentucky plug can be used inside or outside of the bedroom as either a life saving tool or a fun way to spice up your time in the bedroom.

When you insert your thumb into another person's orifice, mainly the anus, resulting in pleasure. Usually only done during sexual activities, the phrase was made popular when Kentucky Ballistics 50-cal blew up, and he had to put a thumb in his next so he wouldn't die.

When you need to, for whatever reason, plug a human orifice with your thumb. Sometimes you need to Kentucky plug the hole in your neck that is rapidly leaking blood. Other times, you need to Kentucky plug your girlfriend's asshole because it's Tuesday and you haven't plugged it since Sunday and she's itchin' for a pluggin'.
Mr. Herrera: Scott gave me the Ol' Kentucky Plug last night!
His friend: dude... gay....
Mr. Herrera: No, this time he was just plugging a shrapnel wound in my leg...
His friend: What do you mean "this time"... Did he Kentucky Plug you some other time?
Mr. Herrera: *abruptly changes subject*
