A certain level of being high accomplished whilst smoking in a bunker.
The phrase, “being bunker high,” is originated in the plains of Denmark. It describes a certain level of being high were one is in a constant haze of laughter, and everything seems manageable. This uplifting sort of being high is easiest accomplished in a bunker with little spaciousness, lots of candles, chill music, mouth dripping munchies and good company.
Dude 1: "Dude, that weed is so good, I can't stop laughing"
Dude 2: "That's because your bunker high dude"
