An instance where a substance is being smoked, whether it be cigarettes, cigars, hookah or illegal substances and a thick cloud of smoked being exhaled by another in a group happens to drift and blind another member of the group momentarily much like a thick fog on a rainy London morning
Fucking Mike took the biggest rip off of that hookah and it drifted into my face, gave me a bloody London Fog!
