BOB

A member of a subset of Bernie Sanders supporters who refuses to accept the outcome of primary elections and insists the process was rigged by the DNC. Typically, a BOB will refer to Democratic politicians and others that they don't like as Republicans, Republican-lights, or corporate whores. Most notably, BOBs enjoy referring to the majority of Democratic voters and the candidates who overwhelmingly defeat their preferred candidate as "The establishment".
