Birkenstock Gestapo 

Term used in reference to a group of stereotypical, postmodern hippy-wannabes.

Not to be confused with true, original, peaceful hippies of the 1960s, this modern day self-proclaimed socially conscious group often have extremely aggressive, militant views and attitudes, and will resort to physical measures during the course of their unwarranted, misdirected "peaceful protests".

Readily identified by their stereotypical, common choice of footware (see, Birkenstocks), members of this social classification can be found wherever protests are being held, regardless of how valid the cause may be.

see also Hipptards.

QFT (in Berkeley, California):

Birkenstock Gestapo: "A guy who has just moved here from Nigeria and became a US Citizen can't be called an African American because his ancestors weren't slaves."

Me: "WTF?!"

Birkenstock Gestapo: "Why do you hate so much?"

Me (confused as all hell): "Erm... What are you talking about? Then, *mocking*:Dude, Why don't you stop swimmin' at the bottom of the bong, man."

Birkenstock Gestapo: "Nazi" *snarls*

Me: /facepalm *walks away laughing*

Birkenstock-pilled 

It refers to someone recognising the patriarcal systems that exists in the world.

A play on the term "red-pilled" based on the movie Barbie where Barbie is offered the learn the truth by picking flat Birkenstock (and travelling to the real world) or picking a a pair of pink high heels that reject that for keeping things as they are and ignoring reality.

I used to think men should be paid more but then I got Birkenstock-pilled and realised women deserve to be paid the same for equal work
