Resting Crank Face

The beatific expression of an extremist - either on the left or the right - who holds opinions that only they and their crank-friends subscribe to. Resting crank face can involve smiling benignly, while spouting crank theories to crank comrades 'The moon landings were faked by Stanley Kubrick' or 'The illuminati is controlling Congress' or 'The Joos did 9/11'
