A game played in cars that is similar to punch buggy or spotto, whereby players yell put “GREENO!!!!’ when they see a green vehicle and punch someone sitting next to them. Parked motorised vehicles do not count. Only one greeno can be claimed per vehicle. Under special circumstances the spotter (the person who spotted the green vehicle) is allowed to punch a person of their choice twice if they are a naysayer such as L.C. If the naysayer still does not believe the game is a valid legit thing (despite it being on urban dictionary) the spotter is allowed to punch the naysayer an additional time.
