I was starting to have sex with a girl off tinder when she suddenly started her period, I gave the the Kentucky thumb and let her give me head instead.

As defined by the AK guy, a life-saving thumb that enters your jugular to stop yourself from bleeding out after firing an over-powdered .50 caliber SLAP round which explodes your bolt action Serbu RN-50. This thumb is necessary to saving your life since a fragment of the exploding bolt action rifle has lacerated your jugular, so without your Kentucky Thumb you would've die on the interstate driving to the nearest hospital as your father speeds past triple digits in your Silverado
