You've got the answer already, but I believe it got the name from Jack Johnson.

Some opponents of his are visibly hurt on film, but he clinches and keeps them standing up until they recover. Literally carrying them, and thus carrying the fight to make it more worth the money of the people who have come to watch.

Also I believe a bit of it was just him playing with his food so to speak. He definitely had that type of stuff in him.
