Noun. - To "milk" a persons spine by roughly rubbing their lower back all the way to the brain stem, normally when the recipient is in a "praying to Alla" pose. During this, as part of Raver tradition, a prayer to the rave gods is normally said by the person giving the serotonin shot. At the end the the giver pulls the receiver up on to his/her knees quickly and Vick's Inhaler is blow in their eyes (a sea-breeze) and the receiver is informed that they are free. The receiver generally goes limp and is placed on the ground to enjoy the effects.
NOTE: Only enjoyable if the receiver is under the effects of MDMA.
