yo-yo

(n.) a form of childhood torture referred to as a game, usually inflicted by older children (most often siblings) upon younger ones. The aggressor will pin their victim laying face-up on their back, sitting on their chest and making sure the victim cannot move their arms. Then the aggressor leans over the poor kid and dribbles a string of spit towards the kid's face until it almost reaches, then sucks it back into the mouth. Odds are, the longer this action is repeated, the victim will end up wearing saliva. This ritual generally lasts until either: 1) the aggressor tires of his fun, or 2) an adult intervenes.
