Big Firey (or flippin') Blue Flame. Used as a saying to ward off a large inferno or warn someone when someone disobeys basic fire-safety rules.
My friend put the paper plate on the gas range and quickly turned it off. So I said BFBF!

I yelled "Dude! BFBF!" as K. Gibler went to set the 5 year old newspapers onto the halogen torcheire which was turned on.
