Douchenism 

The act of completely dedicating oneself to being a douche to almost biblical levels. For most, being fully dedicated to douchenism is so engrained that they don't even realise their own membership has been bought, paid for and passed on to their offsprings, all while making any other members of society, (particularly non douchenists), groan in pain with every action they take.

Jim, "Look at that guy pushing in line at the ATM. I decree that he prays at the alter of douchenism."
Billy, "I do concur with your observation good sir"
