Kentucky thumb

While playing the giver in the "doggy style" sex position, insert your thumb into the rectum of the reciever.

I Kentucky thumb'd your girlfriend last night.

Thumb-butting

When you are hitting it from behind and have your thumb in her butt at the same time. Thumb-butting it.

She seemed like she wanted it so to test the waters I was thumb-butting it.
