Get the Leviathan mug.
An interconnecting series of psychological, sociological, and technological forces that errode our humanity, deny our freedom, and alienate us from nature. The opposite of anarchy.
Leviathan is all around us, so much so that we cannot identify it easily. It has a social contract, an invisible hand, and pink hair.

Get the Leviathan mug.
An enormous, ocean going turd that, before launch, requires the presence of a Royal, bunting strung along its length, champagne smashed over its bows, a brass band and cheering, hat tossing crowds, before it is allowed to prowl the open seas. A truly gargantuan shit, generally armed with a minimum of eight fifteen inch guns and fitted with Jarrow boilers and armoured decking.
Boy oh Boy! I had an Indian last night and this morning it spawned a Leviathan! My asrehole will take weeks to recover after launching that baby!
