You can say that someone or something is “going down”, and you can say that it’s “going up in smoke”, but nothing ever seems to “go down in smoke”. Which seems to me a great way to double your threat with little effort. Some camper keep fragging you? Griefer steal your earthworm munch? Save your other, small threats. Tell them they’re “going down in smoke”. That’ll put a shiver in their timbers, if they’ve got timbers to shiv.
But that’s all beside the point.
The point is: Montreal is going down in smoke, literally.
