A motion performed by hippies, most typically in a concert or music festival setting, and with the aid of mind expanding drugs. The motion is defined by semi-rhythmic swaying with ones hands tossed up the air.
The setting at last night's Phish concert could be best described as one big Vermont State Dance party.

or...

Patty took a lot of LSD at the concert and proceeded to do the Vermont State Dance all night long.
