Wank slap

A funny prank to play whilst drunk at a party or sleep over. Much like placing cream in the open hand of a passed out or sleeping person and tickling them on the face so they slap cream in their face. This is very similar, only using a different kind of "cream". One masturbates on to a piece of tissue, and places the used tissue dry-side-down on to the victims hand. The victim is then tickled on the face to entice them to scratch to itch, and then end up with a wanky tissue stuck on their face.
