when a person is inhaling nitrous gas from a balloon and accidentally lets go, so the balloon flies around the room. because the gas is valuable the individual and others will jump and dive after the balloon. this is likely the most active you will ever see a hippie.
jon got injured playing wookieball when he dove from the bed after the balloon and faceplanted because he was high on nitrous. i don't even know how he twisted his ankle but his face got bloody.
