An adjective describing pseudo-hippie yuppie bullshit practices. Usually refers to ingenuine hippie resembling or environmental efforts, such as using your 401k a year to buy a hybrid car and wear crocs. There are generally a lot of hippydippy organizations standing outside at concert lines or festivals that like to spam your e-mail address with useless petitions to sign and such. Mostly, the types to engage in hippydippy activities are rich people and teenagers who drive 35 miles to get to their local Earth Day festival where they will buy a hacky sack and tie dyed t-shirt, but eat a $5 piece of pizza instead of ordering from the vegan menu.
"Get your hippydippy crystals away from me, my chakras are just fine thanks."
"My friend is on this new hippydippy cleansing diet, you only eat hummus and granola."
A derogatory name for hippies used predominantly by squares in the late 1960s and early 1970s.
Look at those stupid hippy dippy peacenik freaks with their girly long hair and flowery bell bottoms laughing at me and my pressed brown slacks, white shirt, polka dot bow tie and crew cut as I walk around campus distributing Nixon campaign pamphlets. Just wait until I inherit my daddy's insurance business and they come begging me for a job, we'll see who's laughing then.
