stand face to face with your friend, place a hand on each of their ears. slowly roll their head in a circle to loosen their neck, then rapidly vibrate your right or left hand, whichever is easier, forward and backwards, lightly and quickly while using the other to guide their head slowly side to side. bumps them WAY the fuck up!!!
squeeze your friend's forearm just under the elbow to constrict and have them pump the hand of the arm you're holding to increase pressure. Have them keep doing this till you see their veins begin to pop out or their skin redden a little. On your queue, have them hold their hand open and palm up and smack it as hard as you can with your palm, one or two slaps is usually plenty, creates a really interesting rushing and tingling feeling.
