I don't understand why you can't understand simple concepts. First of all, the Wiki entry says "likely." I provided a Wiki that says it was in reference to Biden being "mentally slow" or, as Biden's biographer said, Biden's incoherence. Ultimately, the name stuck because "Sleepy Joe" covers everything: Joe's mental decline, Joe's lack of balance, Joe's poor sense of direction, Joe's inability to follow directions, that sleepy look on his face in the later half of his term as POTUS, he lethargic movement, and even Joe's occasional poorly timed naps. I don't know what Trump was referencing, but I suspect like the rest of us he was using as a catch all. Personally, I don't care how Trump was using it, I'm pretty damn sure the rest of us weren't using it literally. So this is the ~10th different way I've explained it to you and I'm sure you'll continue to insist we were using it literally.
