A characteristic of the male human. The morning stiffy occurs at about 6 AM. Hard to ignore by the male, it should be hidden from the human female, lest she think that it is a lollipop....
"Well, I woke up with a morning stiffy... so I wanted to do up the old lady, but she said, 'Get away from me !!'"....

"So I gave it to 'er in the butt...."
