Little Jack Hornher 

Based on the children's nursery rhyme this sexual act entails taking a girl from behind doggystyle and inserting one's thumb in her anus upon climax.

As in....Little Jack Hornher... he stuck in his thumb, made the girl cum, and said, "What a good boy am I".

When your thumb is numb and stick it up your bum like little jack horner did in his self titled poem. When you pull out your thumb, there's a nugget on it.
"...Eating a Christmas pie;
He put in his thumb,
And pulled out a plum,..."*-

a classic nursery rhyme by mother goose

little jack horner

Eating a Christmas pie;

And pulled out a plum,
And said 'What a good boy am I!'
