SYBIL DANNING 

B-Movie Actress of the 1980's and early 1990's best known for her scantily-clad characters and gratuitous nudity, blending a tough persona and ass-kicking attitude with raw sex appeal. The 80's archetype of "tough and sexy", the kind of actress who'd fanboys bow down to and worship at her feet, even licking her boots to pay homage!

Ever see a movie with Sybil Danning in it? That chick filled out a bikini like a friggin' Amazon but I wouldn't get too close, she might cut ya balls off!

Anarcho-Syndicalism 

Anarcho-syndicalism, also referred to as revolutionary syndicalism, is a theory of anarchism that views revolutionary industrial unionism or syndicalism as a method for workers in capitalist society to gain control of an economy and thus control influence in broader society.
Syndicalists consider their economic theories a strategy for facilitating worker self-activity and as an alternative co-operative economic system with democratic values and production centered on meeting human needs.

worker A: I believe in equal labor, we don't need greddy boss, we're tired of resisting wage slavery in the capitalist society. We want to be free! Liberation of the working class.
worker B: I agree! Long Live Anarcho-Syndicalism
