kentucky thumb

When you blow up your thumb with explosives so it swells and needs stitches, in order to use it sexually because your dick isn't big enough for her.

She was going to leave me because of my micro penis. So I threw some SLAPP rounds down range until my 50 exploded. Now my Kentucky thumb will keep us together for 2 more weeks.
