Stuck in his craw
Does anyone know where this expression comes from, I have heard it used in a negative context: "stuck in his crawl that they made him retire at the age of 65", "Apparently, this has stuck in his crawl ever since. I know, because he would send me emails every once in a while with some cutting or derogatory comment". Please help
It's craw, not crawl. One gets obsessed with something when you can't digest it and get over it.
Literally, "craw" means the crop [digestive organ] of a bird or the stomach of an animal (American Heritage Dictionary).
