The act of spitting out cum into the palm of your hand and reaching up and putting it on the erect penis above you.

Usually done to inflict pain on the male when the recipient was not warned of its arrival. Many men find it unpleasant or even painful to have their diving board touched after he shoots a hot load. But can be done to try to keep the erection stiff a bit longer and or encourage an additional orgasm.
A: "I can't believe he just shot in your mouth without asking. I hope you got him back good" "Hell yeah I did. I know how to grease the high board. You should have seen him squirm."

Sorry Baby; just use it to grease the high board. I think I can shoot another load.
