I've always heard that if your cigarette goes out by itself twice that it means danger is around. I think this traces back to the vietnam war, when soldiers used to get shot by lighting their cigarettes at night and by doing so, the enemy saw the glow in the wilderness.
Can anyone think of others?
I've always turned one cigarette upside-down in a pack since I first learned to smoke. My friends and I used to refer to this cig. as "a lucky." Where did this urban legend originate from?
