A game where you take turns putting ones hand on top of the opponents head, and dragging it hard in any direction, saying the word "sparns" as you do. Can also be done randomly to an unsuspected person.
Games can sometimes result in a nasty case of whiplash, which can ensure an easy victory.
Guy 1: 'watches t.v.'
Guy 2: 'sneakes up from behind'......."SPAAAARNS"
Guy 1: "OWWW!!!!!"
