Gluck

The process of inverting the human vertebrae to reach a position of self-pleasurability. Simply apply some glen 20, sit down, lean back and relax your anus. once the outer rectum cavity has reached max dilation, flop out your johnson and wait for the next bass drop. Upon arrival of the drop, proceed to frosty your bellend and pressurize your scrotum untill a bright purple colour is identifiable. At this stage, your sphincter should be housing at least half the bottle of glen 20, and your tally-wacker should be solid ice (also known as absolute zero). The next stage, better known as schouto's favourite, requires years of mastery in the craft of Docking.
