Birkensocks 

Hippies and wanna be hippies who wear birkenstocks with socks to keep their feet warm in the cold months. They looks like tools because sandals are not supposed to be warn with socks! Duh

Crazy hippies wearing birkensocks trying to keep their dirty feet warm in the winter with out giving up the sandals- mostly because their too stoned to find new shoes.

Birkenstocks on the ground 

The presence of the popular sandal at an event or gathering. The preferred footwear for hippies, lesbians, old people and preppies.

"There were plenty of Birkenstocks on the ground at the Berkeley alumni reunion."

Birkenstocks 

Sandals worn by liberals, women in Vermont, and for some unknown reason, evangelical youth pastors trying to appeal to young adherents of Christianity.

Pastor Mike has a goatee and wears Birkenstocks--he looks like a pothead for Jesus when in reality his only addictions are online porn and energy drinks.

Birkenmocks

Birkenmocks are any type or brand of fake Birkenstocks. Hence the stem word "mock". Birkenmocks are cheaper than the actual hippie shoes and can often be found on the feet of cheap/broke activists, treehuggers, peacniks, along with many lazy high schoolers. These shoes say "I'm a hippie on a budget".

Mari was too broke for the real thing, so she bought some Birkenmocks from Payless.
