Obama Derangement Syndrome

Obama Derangement Syndrome is an informal brain condition affecting mainly conservatives, causing them to fear and/or hate President Barack Obama, which in turn also caused their general hatred of liberals, even after Obama left office. The disease first reached America in 2008 and hasn't regressed a decade later. In fact, the condition has gotten worse, as evident by it causing the Tea Party and alt-right movements. To make it simple, it turned Conservatives from just simply Bible Thumpers into far-right, authoritarian clowns who want a fascist ethnostate with Christian Sharia.

It is unknown who first coined the term, but it first appeared on Urban Dictionary on February 27, 2008 by user:flyfish (Link).
