When it's "that time of the month" and the flow is heavy, so you reach behind yourself and down between your legs to plug it with your thumb, and proceed with anal.
Scott was bleeding so bad from his .50 SLAP round failing, and I didn't have a first aid kit ...so I decided to just give him the Kentucky Plug. I probably should've stopped with just the thumb, but the look on his face when I started unbuttoning my pants was priceless.

Inserting your thumb inside someone's ass, vagina or jugular vein. Usually it is done by men or women with large round thumbs that have thin dull fingernail, it is also used if your jugular is severed or slightly punctured.

Quickly eating 6 cans of beans in a row and then putting in a butt plug, and resisting all urges to remove the plug due to gas caused by the beans.
I have to shit so bad but I am Kentucky Bean Plug-maxxing and it hurts like all hell
I tried Kentucky Bean Plugging once, it was so painful why would you ever do it.

Sticking a thumb in her while she is on her period, so she doesn’t bleed out while you shove your other appendage in her asshole.

When having sex with a woman, and mid-coitus she either farts or starts squirting, and you stick your thumb in whichever hole is leaking to plug the hole until you finish.
