Birkenstocks 

the expensive clogs or sandels that are for both men and female people. They are usually around $120.00. They are also very comforable and are really preppy. Every big prep should have them.

The Birkenstocks are like the best shoes ever

Birkenstocks 

Ugly ass shoes that hippies or preps wear usually with bluejeans, and are retarded enough to pay over 100$, wear them on a day it's going to rain, then complain to everyone about them getting wet. The also make feet smell horiffic. if you see somebody wearing these tell them to keep them on.

Prep: " omgz, I like, can't believe these got wet! I had to hurry to class, and I slipped in the halls, and my feet are wet, so feel sorry for me!"

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.

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*
