much like a dutch oven but instead of farting in your own blanket and exposing it to yourself u fart in a friends blanket (sleeping or awake) and put it over his or her head.
Dylan: "Bob are you awake?"
Dyan: im goin to vermont oven this SOB..... Lifts bobs blankets and rips a huge fart.
Bob: takes a huge wif while sleeping. "WTF was that"?
Dylan: "haha u just got vermont ovened!!!!"
