Idioms and Phrases

Something that might hasten or contribute to one's death, as in Every cigarette you smoke is another nail in your coffin . This expression, alluding to fastening down a coffin lid, is today almost always used for a harmful habit such as tobacco use (giving rise to the slang term coffin nail for a cigar or cigarette). The idea was first expressed in an ode by Pindar (the pseudonym of John Wolcot) in 1792: “Care to our coffin adds a nail, no doubt.”
