Sorry but this has been bugging me. Americans and now people over here are using the term "Kick Back" to mean relax or take it easy. I cannot see any way that kicking anything back is relaxing or how it can describe relaxing. If I laze in a chair I have not kicked anything back either. Does anyone here know where the term came from and how it got to mean what it means. Most american stuff is fairly easy to get to the meaning or origin but this one is not making sense to me. HELP!
