hippie dippie

a.k.a. hippie dippy

If something is unique, weird, awesome, amazing, or cool... it is considered hippie dippie. It's what a hippie would say or do or use or wear.

For example, "Why does President Trump hate wind turbines? Because his political base wishes we could go back to the 1950s, so they love it when he mocks hippie-dippie, unmanly things like wind and solar power.
