My understanding is that FFS means something like For Fu*k's Sake
And PC (from "Politically Correct") is a phrase used by trumpists in a derogatory way towards those who care for minorities for example
By the way, the trumpist will soon stop laughing, they will soon realize they got fu*ked cause trump is appointing billionaires (not the type who care for trailer trash) to his cabinet including for secretary of health a rabid proponent of abolishing obamacare: millions of trumpists just voted themselves out of medical insurance.
