This is a sex term describing when.....
A guy goes on the pull and finds a girl he thinks he has a chance of havin sex with that night, and so feeds her with drinks till its almost inevitable. They end up round her place but shes so drunk, she passes out on the bed before they get their clothes off. The guy then, knowing he wont get what he came there for, flips her onto her back, wanks off and sprays his load down the middle of her spine.
