A trippy, psychedelic (pleasing to those under the influence of psychedelics) camp or art feature at a music festival or Burning Man.
“Did you see Sunflower and Himay’s beautiful camp at Electric Forest? Total tripper trapper the wooks never wanted to leave.”
“What was that giant, color changing LED light tarp, tapestry thing everyone was laying under and staring at at Burning Man?”
“Oh that was the tripper trapper.”
