Today’s idiom: cold turkey
Meaning: quitting an addiction
Origin: Originally found in the 1920’s to mean speaking plainly, the current use of the phrase came about later. I found two different opinions on the metamorphosis of the meaning. One of the opinions is that, just as it used to mean to speak directly, the act of quitting cold turkey is a direct approach, without tapering off or phasing something out. The other idea I found is that people who stop using drugs resemble a cold turkey, with their body’s blood going to their internal organs after they stop using.
