Kentucky Thumb

When you sever an artery, plug the bleeding artery, and then shove it up a girls ass while firing slap rounds out of your .50 cal

Person 1: Have you heard about Scott?
Person 2: Yeah He gave his wife the Kentucky Thumb a few weeks ago

Scott, Don't fire slap rounds out of your .50 cal, you can't do the Kentucky Thumb Again.

on the tip of my thumb

The maddening feeling when that perfect emoji disappears from your keyboard just when you need it.

Man, where’s that emoji with the squiggly smile?!? It’s on the tip of my thumb—but I’ve scrolled forever and still can’t find it!
